x = 30
(x + 30) = 30 + 30 = 60 °
Since the sum of the two angles is a 90° angle, the equation becomes:
x + (x + 30) = 90
2x + 30 = 90
2x = 60
x = 60/2
x = 30
Thus, x = 30.
(x + 30) = 30 + 30 = 60 °
Since the sum of the two angles is a 90° angle, the equation becomes:
x + (x + 30) = 90
2x + 30 = 90
2x = 60
x = 60/2
x = 30
Thus, x = 30.
