Question

A pair of parallel lines is cut by a transversal. What are the measures of the two marked angles?

- 8x + 8/
-6x + 20
Σ

56° and 56
OB 40° and
65° and 115°
75° and 105

Answer 1

It is a. 56 and 56

Answer 2

Option A. 56° and 56°

Explanation:

we know that

`(-8x+8)^o=(-6x+20)^o` ----> by alternate interior angles

Solve for x

`8x-6x=8-20`

`2x=-12`

`x=-6`

Find the measure of the marked angles

substitute the value of x

`(-8(-6)+8)=56^o`

therefore

56° and 56°
