Can someone with the problem in the picture but also explain exactly how u got the answer cause every time i ask a question nobody explains how they got certain answers. pls it’s urgent!

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

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
