Answer:

Option A. 56° and 56°

Step-by-step explanation:

we know that

[tex](-8x+8)^o=(-6x+20)^o[/tex] ----> by alternate interior angles

Solve for x

[tex]8x-6x=8-20[/tex]

[tex]2x=-12[/tex]

[tex]x=-6[/tex]

Find the measure of the marked angles

substitute the value of x

[tex](-8(-6)+8)=56^o[/tex]

therefore

56° and 56°

Answer:

It is a. 56 and 56
