Question

One angle is three times another if the angles are complementary find their measurements

Answer 1

complimentary angles add up to 90 degrees.

x + y = 90
x = 3y.....one angle is 3 times the other

3y + y = 90
4y = 90
y = 90/4
y = 22.5 <== this is one angle

x = 3y
x = 3(22.5)
x = 67.5 <== this is the other angle
