Answer: x = 103
Explanation:
this is a 90 degree angle indicated by the box in the corner of the angle.
90 degree angles total 90 degrees.
X - 15 + 2 = 90
move the numbers to the other side of the equal sign to isolate the X
by doing the opposite
x = 90 + 15 -2
x = 103
check your work, X - 15 + 2 = 90
103 - 15 + 2 = 90
answer is correct
