Answer 1

Answer:2x+40=180

Explanation:

You want to equate everything for 180 since it's on a straight line

Therefore

(x+30)+(x+10)=180

x+x+10+30=180

2x+40=180

Answer 2

Explanation:

Angle GHI + Angle IHK = 180 (Angles on the same straight line)

(x + 30) + (x+10) = 180

x+x+30+10 = 180

2x + 40 = 180
