Question

Seven times the complement of an angle is 10 less than 3 times its supplement. Find the angle.

Answer 1

Heya user! Here is your answer.

Let angle be x.

Measure of its compliment = ( 90 - x )

Measure of its supplement = ( 180 - x )

7 ( 90 - x ) = 3 ( 180 - x ) - 10

630 - 7x = 540 - 3x - 10

- 7x + 3x = 530 - 630

- 4x = -100

x = $\frac{100}{4}$

x = 25

Answer 2

7(180-x)=10-3(90-x) here is your answer then solve it
