Answer:

Explanation:

Vertically opposite angles are congruent.

∠A = ∠C

∠A + ∠C = 254

∠A + ∠A = 254

2∠A = 254

∠A = 254/2

∠A = 127

Linear Pair: In two adjacent angles, if the non common arms are opposite rays, then they are called linear and they add up to 180

∠A + ∠B = 180 {linear pair}

127 + ∠B = 180

∠B = 180- 127

∠B = 53°
