Question

Two angles are Complementary to each other. One angle is 30 degrees what is the measure of the other angle

Answer 1

Complementary angles equal to 90 degrees.
so, you are given that one angle is 30 degrees
the other angle is unknown, x
30 + x = 90
subtract 30 from both sides
x = 60

The measure of the other angle is 60 degrees.
