## The sum of two complementary angles is 90°. For one pair of complementary angles, the measure of the first angle is 15 less than twice the m

The sum of two complementary angles is 90°. For one pair of complementary angles, the measure of the first angle is 15 less than twice the measure of the second angle. Write a system of equations that can be used to determine the measure of the first angle, a, and the measure of the second angle, b.

•a+b=90

a-2b=15

•a+b=90

2b-15=a

•a+b=90

2b+15=a

•a+b=90

2a-15=b

## Answers ( No )

Answer:a+b=90

a=(2b)-15

Step-by-step explanation:Let

a—————> first angle

b—————> second angle

we know that

a+b=90

and

the measure of the first angle is 15 less than twice the measure of the second angle

a=(2b)-15

A system of equations that can be used to determine the measure of the first angle, a, and the measure of the second angle, b is

a+b=90a=(2b)-15
