Question

if two angles are supplementary and one is double to the other, then the larger angle is
​

Answer 1

answer is 120

Step-by-step explanation:

let x and y be the two angles

x+y=180-----(1)

x=2y----(2)

on substituting value of x in (1) from (2) we get

2y+y=180--3y=180---y=60

larger angle=x=2y=2(60)=120

so the larger angle is 120

Answer 2

Step-by-step explanation:

Let one angle be xº

then other angle is 2xº (As twice of one angle)

Since two angles are supplementary

x + 2x = 180º

3x =

180°

180

3

One angle is 60°,

Other angle 2x = 2 x 60° - 120°
