Question

I need somebody’s help

Answer 1

C

Explanation:

The 2 angles are same- side interior angles and are supplementary, thus

3x - 5 + 2x - 15 = 180, that is

5x - 20 = 180 ( add 20 to both sides )

5x = 200 ( divide both sides by 5 )

x = 40

Thus

3x - 5 = 3(40) - 5 = 120 - 5 = 115°

2x - 15 = 2(40) - 15 = 80 - 15 = 65°

Answer 2

x= 40

so

3x-5= 115

2x-15= 65

Explanation:

C is the correct answer. I see that you put a mark on that choice so you are right if you thought that. I hope this helps!
