Answer:

x = 27

Step-by-step explanation:

Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.

3x - 10  + 2x + 10 + 45 = 180

Now simply silve the equation to find x.

5x + 45 = 180 \\ 5x = 135 \\ x = 27

There is your answer.
