Question

1. If we had two angles that are complementary and <1 = 55 degrees, what is the measure of the second angle?

Answer 1

Two angles are complementary if they sum to 90°. So, if one angle is 55, the other angle must be such that

$55+x=90$

Similarly, two angles are supplementary if they sum to 180°. So, if one angle is 10, the other angle must be such that

$10+x=180$
