The sum of the angles is equal to 90° as it is a right angle.

Let us find x solving the equation. Doing so, we have:

x+3 +x - 1 + x +1 = 90

x + x + x + 3 - 1 + 1 = 90 (Organizing)

3x + 3 = 90 (Adding like terms)

3x = 90 - 3 (Subtracting 3 from both sides of the equation)

3x = 87 (Subtracting)

x = 87/3 (Dividing by 3 on both sides of the equation)

x = 29 (Dividing)

The answer is x= 29.
