The sum of the measures of the two adjacent angles is equal to 90 degrees. Therefore, the equation for the two adjacent angles is:
(x + 18) + x = 90
Simplifying:
2x + 18 = 90
Subtracting 18 from both sides:
2x = 72
Dividing both sides by 2:
x = 36
So the two adjacent angles have measures of 36 + 18 = 54 degrees and 36 degrees.
If two adjacent angles with measure (x+18) and x are inside a 90 degrees angle, what is the equation for the two adjacent angles?
