Step-by-step 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
Answer:2x+40=180
Step-by-step 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
