Answer:

∠a = 3x -12 ( Being corresponding angle)

Now

(3x-12) + (2x + 2) = 180 ( Sum of straight angles)

5x - 10 = 180

5x = 190

x = 38

m∠a = 3x -12 = 3*38 -12 = 102

Answer:

102°

Explanation:

(3x - 12)° + (2x + 2)° = 180°

5x - 10 = 180 ⇒ x = 38

m∠A = (3x - 12)°

m∠A = (3×38 - 12)° = 102°
