Answer:
40,40 and 100
Step-by-step explanation:
You know the first two angles are identical, so let's call them x.
The third angle is 20 more than twice the measure of either angle, which means 2x+20.
The angles of a triangle add up to 180 degrees.
(x)+(x)+(2x+20)=180
4x+20=180
4x=160
x=40 degrees
This means the angle measures equal 40 degrees, 40 degrees, and 100 degrees.

Answer:
The given expression is equivalent to -x
That is 
Now Verified that the two expressions are equivalent
Step-by-step explanation:
Given that Genevieve wants to verify that One-fifth (5 x minus 20) minus one-half (4 x minus 8) is equivalent to Negative x
It can be written as below :

Now we can verify the expression is equivalent or not :
Taking LHS

( by using the distributive property )

( adding the like terms )
=RHS
Therefore LHS=RHS
Therefore the given expression is equivalent to -x
That is 
Now Verified that the two expressions are equivalent
Answer:
y = 1/2x + 2
Step-by-step explanation:
m = -2, (3, - 1)
y - - 1 = -2(x - 3)
y + 1 = -2x +3
y = - 2x + 2
Perpendicular line slope: 1/2x
y = 1/2x +2
