Question 102746
Hello!

I'll just answer you're questions ok?

1.Find the measure of an angle that is twice as large as its complement.

Representation:  let x be the measure of the angle's complement,and 2x be the measure of the angle.

Equation:  2x+x=90
Solution:
3x=90
x=30
Final Answer: 30

2.A supplement angle is four times as large as the angle. Find the measure of the angle.

Representation:  let x be the measure of the angle,and 4x be the measure of the angle's supplement.

Equation:  4x+x=180
Solution:
5x=180
 x=36
Final Answer: 36

3. The measure of a complement of an angle is three times more than twice the measure of the angle. Find the measure of the angle and its complement.

Representation:  let x be the measure of the angle,and 3(2x)+2x be the measure of the angle's complement.

Equation:  3(2x)+2x+x=90
Solution:
9x=90
x=10

Final Answer: the angle is 10,the complement is 80.
