28

Step-by-step explanation:

Triangle on the right id dilated with scale factor 2 ( the sides of the other triangle are double (17-34      8-16     15-30

Dilations preserve angle measurement

C=90 + B=62=152

All triangles sum up to 180

180-152=28

Angle A=28

Angle A is corresponding with angle D

So angle D is also 28
