in an oblique triangle two sides measure 6cm and 12 cm and the angle across from the side that is 12cm in length measures 58°. to the nearest whole, what are the measures of the other two angles
Answer:
25° and 97°
Step-by-step explanation:
Oblique triangle : any triangle that is not a right triangle
Use the sine rule to find one of the unknown interior angles:
[tex]\dfrac{sin(A)}{a}=\dfrac{sin(B)}{b}=\dfrac{sin(C)}{c}[/tex]
where A, B and C are the interior angles of a triangle, and a, b and c are the sides opposite to the interior angles.
[tex]\implies \dfrac{sin(58)}{12}=\dfrac{sin(B)}{6}[/tex]
[tex]\implies sin(B)=\dfrac{6sin(58)}{12}=0.4240240481...[/tex]
[tex]\implies sin(B)=25.08890446...=25 \textdegree \ \ \textsf{(nearest whole)}[/tex]
Sum of interior angles of a triangle = 180°
⇒ Missing angle = 180 - 58 - 25 = 97°

x - 8 = 0.5x - 4
2x - 16 = x - 8
x = 8
Please educated people solve my question.. i asked it an hour ago nobody knows it
AB = AX+XB = 6+18 = 24
The ratio of AB to AX is AB/AX = 24/6 = 4
AC = AY+YC = 10+25 = 35
The ratio of AC to AY is AC/AY = 25/10 = 3.5
The results of each division are 4 and 3.5
We do not get the same result, which means that the proportion [tex]\frac{AB}{AX} = \frac{AC}{AY}[/tex] is not true. This is sufficient to prove that the triangles aren't similar. We need them to be in proportion so that we can use the SAS similarity rule.
Answer: The triangles aren't similarGraph 0.04x+0.02y=0.08.
Answer:
see below
Step-by-step explanation:
let's convert it into slope intercept form first as it will get rid of the decimals. so we must get it to follow the form of y = mx + b.
so we must isolate the y variable:
- subtract 0.04x from both sides
- now we have 0.02y = 0.08 - 0.04x, and to follow the form this can also be 0.02y = -0.04x + 0.08
- divide both sides by 0.02
- now we have y = -2x + 4, so we know the slope is -2
now lets find the intercepts:
y intercept => set x=0
y = -2(0) + 4
y = 4
so we have (0,4)
x intercept => set y=0
0 = -2x + 4
-4 = -2x
x= 2
now we have (2,0)
graph it:
with two points (the intercepts) and the slope we can find a graph that looks like this
Jeremiah is factoring 0.64t^24 – 9 by using the rule a^2 – b^2 = (a + b)(a – b).
What will he use for the value of a?
A. 0.8t^12
B. 0.08t^12
C. 0.8
D. 0.64
Answer:
[tex]0.8\, t^{12}[/tex] (assuming that [tex]a \ge 0[/tex].)
Step-by-step explanation:
The rule [tex]a^{2} - b^{2} = (a + b)\, (a - b)[/tex] describes a way for factoring the difference between two perfect squares [tex]a^{2}[/tex] and [tex]b^{2}[/tex].
Setting [tex]a^{2} = 0.64\, t^{24}[/tex] and [tex]b^{2} = 9[/tex] would ensure that [tex](a^{2} - b^{2})[/tex] match the given expression.
Take the square root of both sides of the equality [tex]a^{2} = 0.64\, t^{24}[/tex]. Make use of the fact that for all [tex]x \ge 0[/tex], [tex]\sqrt{x} = x^{1/2}[/tex].
[tex]\displaystyle \sqrt{a^{2}} = \sqrt{0.64\, t^{24}}[/tex].
[tex]\begin{aligned} a &= \left(\sqrt{0.64}\right)\, \sqrt{t^{24}} \\ &= 0.8\, (t^{24})^{1/2}\\ &= 0.8 \, t^{24 \times (1/2)} \\ &= 0.8\, t^{12}\end{aligned}[/tex].

Put the following equation of a line into slope-intercept form, simplifying all fractions.
12x-20y= 60
Answer:
[tex]y=\frac{3}{5} x-3[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx+ b
m = slope
b = y-intercept
Rearrange the equation:
[tex]-20y=-12x+60[/tex]
Divide each side by -20:
[tex]\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}[/tex]
[tex]y=\frac{3}{5} x-3[/tex]
[tex]y=\frac{3}{5} x-3[/tex] is your simplified, slope-intercept form equation.

Answer:
x ≈ 229.8
Step-by-step explanation:
using the cosine ratio in the right triangle
cos72° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{LM}{KM}[/tex] = [tex]\frac{71}{x}[/tex] ( multiply both sides by x )
x × cos72° = 71 ( divide both sides by cos72° )
x = [tex]\frac{71}{cos72}[/tex] ≈ 229.8 ( to the nearest tenth )

and [tex]\sqrt{100[/tex] - [tex]\sqrt{64[/tex] into the calculator you get =2 (the sqrt of 100= 10 and the sqrt of 64=8) (10-8=2)
Answer:
ok so lets just talk about what each one represents
the first one represents the square root of 100-64 so
the square root of 36 is 6
the second one is the square root of 100 minus the square root of 64 so
10-8=2
the first one is 6
the second one is 2
so no

Step-by-step explanation:
a. Total number of marbles = 10
Number of red marbles = 3
Probability = Number of outcomes/ Total number of outcomes
= 3/10
b. Total number of marbles = 10
Number of red marbles = 3
Number of marbles excluding the red marbles

Kiara invested $3,500 into two accounts. One account paid 5% interest and the other paid 7. 5% interest. She earned 6% interest on the total investment. How much money did she put in each account?.
The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.
What are the simultaneous equations that can be used to represent the question?0.05a + 0.075b = (0.06 x $3500)
0.05a + 0.075b = $210 equation 1
a + b = $3,500 equation 2
Where:
a = amount invested in the account that paid a 5% interest
b = amount invested in the account that paid a 7.5% interest
How much was invested in the account that pays a 7.5% interest?
In order to determine this value, multiply equation 2 by 0,05
0.05a + 0.05b = 175 equation 3
0.025b = 35
b = $1400
How much was invested in the account that pays a 5% interest?
a + $1400 = $3500
a = $3500 - 1400
a = $2100

Using derivatives+optimization, find the dimensions of the rectangle of largest area that can be inscribed in an equilateral triangle of side 12.
Check the picture below atop.
we know is an equilateral triangle, meaning that all its interior angles are 60°, and thus if we run a line from the top vertex as you see there, we end up with a 30-60-90 triangle, either way there's an equation to get its height, and anyhow the altitude of it is 6√3.
As the rectangle moves up and down the triangle, with the rectangle having a width of "w" and a length of "L", the triangle that it forms above itself is a triangle, always with a base of "L" and a height of 6√3 - w.
BTW we laid the rectangle as you see on the bottom side, but laying it anywhere else it'd have ended up in the same arrangement.
well, with the bottom of the rectangle beign parallel to that of the side of the circumscribing triangle, the small upper triangle is similar to the containing triangle by AAA, and since we have similar triangles, we can say that.
[tex]\cfrac{6\sqrt{3}}{12}=\cfrac{6\sqrt{3}-w}{L}\implies \cfrac{\sqrt{3}}{2}=\cfrac{6\sqrt{3}-w}{L}\implies L\sqrt{3}=12\sqrt{3}-2w \\\\\\ L=\cfrac{12\sqrt{3}-2w}{\sqrt{3}}\implies L=12-\cfrac{2w}{\sqrt{3}}\implies L=2\left(6-\cfrac{w}{\sqrt{3}} \right) \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{Area of the rectangle}}{A=wL\implies A(w)=w\cdot 2\left(6-\cfrac{w}{\sqrt{3}} \right)}\implies A(w)=2\left(6w-\cfrac{w^2}{\sqrt{3}} \right)[/tex]
[tex]\cfrac{dA}{dw}=2\left(6-\cfrac{2w}{\sqrt{3}} \right)\implies \cfrac{dA}{dw}=4\left(3-\cfrac{w}{\sqrt{3}} \right) \\\\[-0.35em] ~\dotfill\\\\ 0=4\left(3-\cfrac{w}{\sqrt{3}} \right)\implies \boxed{w=3\sqrt{3}}[/tex]
hmmm the way I usually run a 1st derivative test is, by using the critical point and slicing from it just a tiny bit, like say 3√3 - 0.000000001 to check the region on the left and then 3√3 + 0.000000001 to check the region on the right.
Check the picture at the bottom, the 1st derivative test more or less gives us those values, positive on the left-side and negative on the right-side, meaning as you can see in the arrows, is a maximum at that point.
[tex]\stackrel{\textit{we know that}}{L=2\left(6-\cfrac{w}{\sqrt{3}} \right)}\implies L=2\left(6-\cfrac{3\sqrt{3}}{\sqrt{3}} \right)\implies \boxed{L=6}[/tex]
