Question

Does anyone know this???

Answer 1

see explanation

Explanation:

Since the triangles are congruent then corresponding angles are congruent.

Thus ∠D = ∠A and substituting values

2x = x + 31 ( subtract x from both sides )

x = 31

Hence

∠A = x + 31 = 31 + 31 = 62

∠D = 2x = 2 × 31 = 62
