Respuesta :

angle APR, which includes x+64, is congruent to PRD, by rule of alternate interior angles
This assumes that AB is parallel to CD

APR = PRD
x+64 = 110
x+64 -64 = 110-64
x = 46°

Answer:

x + 64 = 110

x = 46

Step-by-step explanation:

You need to isolate the x, so you need to subtract 64 from 110 ( which is 46 ). By you doing that, you need to now subtract 64 from 64 itself.

Would look like this:  x + 64   = 110

                                      -  64   - 64

Which would leave you with x = 46
