If triangle ABC and DEF are congruent, what is the measure of angle E?

∠ E = 83°

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

Thus ∠ C = ∠ F = 47° and

∠ B = 180° - (50 + 47)° ← angle sum of Δ

∠ B = 180° - 97° = 83°

∠ B and ∠ E are corresponding angles, thus

∠ E = ∠ B = 83°

the answer would be c:   ax + b = ax + c
