Question

Seven times the complement of an angle is 10° less than 3 times its supplement
the angle.
of the angles forming a linear pair is four times that of the other, then find its angle.
​

Answer 1

Answer:

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 = 100/4

x = 25
