Question

In order to prove that the two triangles are congruent by ASA, what must you know about the measure of ∠D?

Answer 1

Answer:

Angle D must measure 35°

Step-by-step explanation:

For these triangles to be congruent, ∠A must equal ∠D.

Angles in triangle add to 180:

∠A+∠B+∠C=180

A+58+87=180

A=180-145

∠A=35°=∠D
