Answer:
Step-by-step explanation:
Angle 1 and angle 4 are Alternative angles:
Alternative angles are pair of angles on the inner side of each of those two lines but on opposite sides.
∠1+∠2 =180 sum of straight angle =180 ( angle 2=118)
∠2-∠2=180 ,∠2=180-62=118
∠4+∠2=180 sum of straight angles=180 (∠4=62 degrees)
∠4+118=180 ⇒∠4=180-118 ⇒∠4=62 degrees
∠1=∠4 alternative angles
