<h3>Answer:  x = 45</h3>

Work Shown:

x+x+90 = 180 .... all three angles of a triangle add to 180

2x+90 = 180

2x = 180-90

2x = 90

x = 90/2

x = 45

This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.

Answer:

D would be the correct answer.

As you can see in the second equation, y is already isolated. So, we can substitute it into the first equation, to solve for x.

Let me know if this helps!
