Question

An angle is 10°less than its supplement ,
find the angle

Answer 1

let the first number be x

We know that sum of supplemnt angle is 180

Second number will be 180-x

So, 180-x is supplement of x

Given that number is 10 less than its supplement angle

So,

(180 - x) -10 = x

170 = 2x

x= 85

Answer 2

Answer:85

Step-by-step explanation:let the angle be x

so it will be (180-x) - 10

So x-170+x

x+x=170

2x=170

x=85
