If you can explain that would be great

Answer 1

option D .35

Explanation:

2x+3x+5=180 linear pair

5x=180-5

x=175/5=35

Answer 2

D

Step-by-step explanation: the answer is d because the other half without the equations is = to 180 which is a semi circle. This means that the other half must be 180 too because a circle is 360. I did trial and error and plugged in all the numbers.

Hope I could help!
