Answer:
[tex]x = 27[/tex]
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.
[tex]3x - 10 + 2x + 10 + 45 = 180[/tex]
Now simply silve the equation to find x.
[tex]5x + 45 = 180 \\ 5x = 135 \\ x = 27[/tex]
There is your answer.
