Answer 1

Answer:

x= 35

2x-10+3x+15= 180° (linear pair)

5x+5 = 180°

5(x+1) = 180°

x+1 = 180 /5= 36

x = 36-1

x= 35

hope it helps:)

Answer 2

it's answer will be (b)35

Step-by-step explanation:

As we know that ACis a straight line it means that angle AOC =180 deg

So 2x-10+3x-15=180

5x+5=180

5x=175

x=35
