Question

5. The angles are supplementary and the larger is 20° less than three times the smaller.......​

Answer 1

Answer:

Let's take the larger angle as x

and the smaller angle as y

so According to the Given Condition

x + y = 180

And

x = 3y - 20

x - 3y = - 20

let's subtract these equations

x +y = 180

x - 3y = - 20

4y = 200

y = 200/4

y = 50

Hence the smaller angle is 50 so let's find the Bigger angle

x + y = 180

x = 180 - 50

x = 130

Hence the final answer , the larger angle is 130° and the smaller angle is 50°
