Answer:
[tex]AB\approx 24.22[/tex]
Step-by-step explanation:
In any right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle.
In this case, in order to form the ratio, we're looking for the angle to the bottom right of the triangle. Notice how this angle is the supplement to the angle marked [tex]130.8^{\circ}[/tex]. Since the two angles form one side of the line, we can solve for this angle.
Let's call the angle [tex]\theta[/tex]:
[tex]130.8+\theta=180,\\\theta=49.2^{\circ}[/tex]
From basic. trig for right triangles (refer to first paragraph in answer):
[tex]\sin 49.2^{\circ}=\frac{AB}{32},\\AB=32\sin 49.2^{\circ}=24.2238417809\approx \boxed{24.22}[/tex]

Answers
Answer:
m<F = 44°
length of FH = 15
length of GF = 21
Perimeter of ∆FGH = 50
Step-by-step explanation:
✔️Find m<F using the sum of triangle theorem:
The small box indicates angle 90°. Sum of a triangle is 180°. Therefore,
m<F = 180° - (90° + 46°)
m<F = 180° - 136°
m<F = 44°
✔️Find FH using trigonometric function:
Reference angle = 46°
Length of Opposite side = FH = ?
Length of Adjacent side = GH = 14
Apply TOA because we are concerned with the OPP and ADJ sides:
Tan 46° = Opp/Adj
Tan 46° = FH/14
14*Tan 46° = FH
14.4974243 = FH
FH = 15 (approximated to nearest whole number)
✔️Find GH by applying either a trigonometric function or just simply apply pythagorean theorem:
Pythagorean theorem is given as,
c² = a² + b²
c is the longest side (hypotenuse) = GF = ?
a = GH = 14
b = FH = 15
Thus:
GF² = 14² + 15²
GF² = 421
GF = √421
GF ≈ 21 (nearest while number)
✔️Perimeter of ∆FGH = GH + GF + FH
= 14 + 21 + 15
= 50

Find the equation of the line passing through the point (-6,4) that is perpendicular to the line 5x+3y=5
Answers
9514 1404 393
Answer:
3x -5y = -38
Step-by-step explanation:
The equation of the perpendicular line can be formed by swapping the coefficients of x and y in the given equation, negating one of them. The new constant will be the one that lets the given point satisfy the equation.
given: 5x +3y = 5
perpendicular: 3x -5y = constant
At the given point, the constant is ...
3(-6) -5(4) = -18 -20 = -38
So, the desired equation is ...
3x -5y = -38
Between 02 30 and 05 15, the same day ,the volume of water in a reservoir increased from 1500 L to 14 700 L. What was the average rate of increased in volume of water, giving your answer in L/h?
Answers
Answer:
4,800
Step-by-step explanation:
(14,700- 1,500) / 2 h 45 m
= 13,200 / 2.75
= 4,800 L/h
Time in minutes between 2 30 and 5 15 = 165 minutes= 2.75 hrs
raise in water level = 14700-1500= 13200
the average rate of increased in volume of water, giving your answer in L/h = 13200/2.75 = 4800 L/h

Answer:
x = 48 degrees
Step-by-step explanation:
(2x + 2) + (x + 34) = 180
3x + 36 = 180
3x = 180 - 36
3x = 144
x = 144 / 3
x = 48 degrees
I hope this helps :)
Answer:
B. x = 48
Step-by-step explanation:
(x + 34)+(2x + 2) = 180°. Angles on a straight line
x+2x = 180 - (34+2)
3x = 180 - 36
3x ÷3 = 144 ÷3
x = 48°

Find the total volume of the composite figure below. Round to the nearest thousandth.
Use the π key.
Answers
Answer:
The volume of the composite figure is approximately 3567.198 cubic feet.
Step-by-step explanation:
The composite figure consists in the combination of a right cone and a cuboid. The volume of the composite ([tex]V[/tex]), in cubic feet, figure can be determined by this expression:
[tex]V = \frac{1}{3}\cdot \pi \cdot r^{2}\cdot h + w\cdot H \cdot l[/tex] (1)
Where:
[tex]r[/tex] - Radius of the circle of the right cone, in feet.
[tex]h[/tex] - Height of the cone, in feet.
[tex]w[/tex] - Width of the cuboid, in feet.
[tex]H[/tex] - Height of the cuboid, in feet.
[tex]l[/tex] - Length of the cuboid, in feet.
If we know that [tex]r = 10\,ft[/tex], [tex]h = 10\,ft[/tex], [tex]w = 20\,ft[/tex], [tex]H = 7\,ft[/tex] and [tex]l = 18\,ft[/tex], then the volume of the composite figure is:
[tex]V = \frac{1}{3}\cdot \pi \cdot (10\,ft)^{2}\cdot (10\,ft) + (20\,ft)\cdot (7\,ft)\cdot (18\,ft)[/tex]
[tex]V = \left(\frac{1000\pi}{3} + 2520\right)\,ft^{3}[/tex]
[tex]V \approx 3567.198\,ft^{3}[/tex]
The volume of the composite figure is approximately 3567.198 cubic feet.
3x+4y=−2. 2x−4y=−8
Select the statement that correctly describes the solution to this system of equations.
Answers
Answer:
One solution at (-2,1)
Step-by-step explanation:
3x+4y=−2.
2x−4y=−8
Add the two equations together
3x+4y=−2
2x−4y=−8
------------------------
5x +0y = -10
Divide by 5
5x/5 = -10/5
x=-2
Now find y
2x-4y = -8
2*-2 -4y = -8
-4-4y = -8
Add 4 to each side
-4+4 -4y = -8+4
-4y = -4
Divide by -4
y = 1
Which matrix represents the system of equations shown below?
y = 5
4x = 3
Answers
Answer:
[tex]\left[\begin{array}{ccc}1&0\\0&4\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}x\\y\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}5\\3\end{array}\right][/tex]
Step-by-step explanation:
A matrix is an algorithm that has many applications. It is composed of a series of numbers (typically coefficients of variables) organized in a pattern. When dealing with a matrix, one must always remember the rule (rows by columns). One such application is that a matrix can facilitate the process by which one solves a system of equations.
When given the following system:
y = 5
4x = 3
One can see that not all of the equations have all variables in them. Yet, bear in mind that any number times zero is zero, therefore, one can rewrite the equation such that it has all of the variables if one ensures that the coefficient of the missing variable is (0).
y + 0x = 5
0y + 4x = 3
Now organize this in the form of a matrix, the coefficients of the variable go in a (4 x 4) since there are now (4) elements. The variables are vertically arranged in a (2 x 1), and the equation results are also vertically arranged in a (2 x 1).
[tex]\left[\begin{array}{ccc}1&0\\0&4\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}x\\y\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}5\\3\end{array}\right][/tex]
