Question

The measure of a complementary angle have a sum of 90° angle and angle B are complementary and their measures have a difference of 20° what are the measures of the angles

Answer 1

ok so we know that

A + B = 90

we also know that

A - B = 20

There are a lot of ways to solve this, but I think elimination will be best

A + B = 90

+ (A - B = 20)

-----------------------

2A = 110

A = 55

Therefore,

B = 90 - 55 = 35
