Question

The sum of the measures of angles xand y is 120°. The measure of the angle x is 12 less than the measure of the angle y. Find x and y.​

Answer 1

Answer:
x = 54°
y = 66°

Explanation:

x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
