Question

Find the measure of an angle if seven times its complement is 10 less than 3 times its supplement.

Answer 1

Answer:

7x+10+3x=180

10x=170

x=17 OK friend this is urs answer

Answer 2

Let the no. be x

Its complement angle will be (90-x)

It 7 seven times it's complement =(90-x) ×7

Its suppliment angle will be (180-x)

It is 3 times it's suppliment =(180-x)×3

B.T.P.

{(180-x)×3} - 10 = (90-x)×7

or, 540-3x-10=630-7x

or,530-630=-7x+3x

or, -100=-4x

or, x =25

•The angle is 25°.
