-45.6 is the answer if you evaluate
So you would plug in 0 for a from the beginning since this is numerical slope definition of a derivative
Answer:

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.

Now simply silve the equation to find x.

There is your answer.
