PLS HELP CAN’T FIGURE OUT HOW TO FIND b OR c ASAPPPPPPPPP
Answer:
b = 0.35 ; c = 2.03
Step-by-step explanation:
tan = opposite/hypotenuse
Therefore, tan (10) = b/2
b = 2 tan (10) = about 0.35
Use the Pythagorean theorem to find that c = 2.03
Hi please help i am stuck with this question i will mark for brainliest
And 100. Point
Answer: 9
Step-by-step explanation:
First solve the system (using elimination):
x-y=7...(1)
3x+2y=26...(2)
Multiply equation 1 by -3
-3x+3y=-21
+ 3x+2y=26
-----------------
5y=5
y=1
Substitute y=1 into equation 1
x-y=7
x-(1)=7
x=8
Let a=8 (x=a) and y=1 (y=b)
a + b
= (8) + (1)
= 9
Information provided with us :
x is assumed as a y is assumed as bWhat we have to calculate :
Value of a + b ?Performing Calculations :
Here we have been given with two equations,
x - y = 7 (First equation) 3x + 2y = 26 (Second equation)From the first equation we would be getting a value of x and that value of x we would substitute in the second equation.
⇒ x - y = 7
⇒ x = 7 + y
Now, substituting it in the second equation :
⇒ 3x + 2y = 26
⇒ 3 (7 + y) + 2y = 26
⇒ 3 × (7 + y) + 2y = 26
⇒ 21 + 3y + 2y = 26
⇒ 21 + 5y = 26
⇒ 5y = 26 - 21
⇒ 5y = 5
⇒ y = 5 / 5
⇒ y = 1
★ Therefore, value of y is 1.
Now, substituting this value of y as 1 in the first equation.
⇒ x - y = 7
⇒ x - 1 = 7
⇒ x = 7 + 1
⇒ x = 8
★ Therefore, value of x is 8.
Value of a + b :-
⇒ x = a = 8
⇒ y = b = 1
Now,
⇒ a + b
⇒ 8 + 1
⇒ 9
Henceforth, value of a + b is 9.
Find the measures of each numbered angles
Answer:
∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 35° + 36° = 180°
∠ 1 + 71° = 180° ( subtract 71° from both sides )
∠ 1 = 109°
-------------------
∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then
∠ RVU + ∠ 1 = 180°
∠ RVU + 109° = 180° ( subtract 109° from both sides )
∠ RVU = 71°
In Δ RVU
∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )
∠ 2 + 151° = 180° ( subtract 151° from both sides )
∠ 2 = 29°
-------------------------
∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then
∠ 3 = 71°
Δ UVT has: ∠V₁ = 180⁰ - ∠TUV - ∠VTU = 180⁰ - 35⁰ - 36⁰ = 109⁰
We have: ∠RVU = ∠V₃ = 180⁰ - ∠V₁ = 180⁰ - 109⁰ = 71⁰
ΔRVU has: ∠U₂ = 180⁰ - ∠URV - ∠ RVU = 180⁰ - 80⁰ - 71⁰ = 29⁰
Answer:
∠V₁ = 109⁰∠U₂ = 29⁰∠V₃ = 71⁰Ok done. Thank to me :>
My teacher is trash for math i need help
Answer:
Step-by-step explanation:
The first step is to figure out what the % is on the right.
The total is 100%
The left side is 60%
The right side is 100% - 60% = 40%
Now the 40% represents 28 students
The total number of students is 100%
40%/100% = 28/x Cross multiply
40% x = 28 * 100% Divide both sides by 40%
x = 28 * 100 / 40
x = 70
So the total number of students is 70
60% of them are on the left. 60/100 * 70 = 42
There are 42 students on the left.

In right triangle ABC below, CD is the altitude to hypotenuse AB. If CD=6 and the ratio of AD to AB is 1:5, determine and state the length of BD.
Step-by-step explanation:
the altitude makes a right angle at hypotenuse
cd^2+ ad^2 = ac^2
36+ (h/5)^2 = ac^2
ad/ab = 1/5; ad/h = 1/5; ad=h/5
similarly
bd^2+cd^2 = bc^2
(4/5)^2+ 36 = bc^2
ac^2+bc^2 = ab^2
36+h^2/25+ 16/25h^2+36 = h^2
h= 15
bd/ab = 4/5
bd= .8*15=12

Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
In equation form would be:
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A

The graph is a line.
The graph intersects
the x-axis.
The input x-1 has
many outputs.
The graph is a
vertical line.
Answer:
The input x = 1 has many outputs.
The graph is a vertical line.
Step-by-step explanation:
Hi there!
A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.
Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.
More generally, no vertical line is a function for this reason.
I hope this helps!

Name the three different types of proofs you saw in this lesson. Give a description of each.
One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof.
You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.
