Question

Corresponding parts find m

Answer 1

Answer:

Angle D is equal to 80.

Step-by-step explanation:

We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.

Triangles' angles always add up to 180.

180 - 70 - 30 = 80

angle D is equal to 80.

Answer 2

I think d is equal to 80 I’m not sure
