Question

2 supplementary angles are such that 1 angle is half the other. find the 2 angles​

Answer 1

Answer:

mark me branlist please

Step-by-step explanation:

Supplementary angles means the sum of angles must be 180 degrees. So the two angles which are supplementary and one angle is half of the other is 120 degree and 60 degree .

Answer 2

Step-by-step explanation:

let the one angle be x.

the other angle = x/2

adding 2 angles = 180 (they are supplementary)

so, x+x/2=180

» 2x+x/2=180

» 2x+x = 180×2

» 3x = 360

» x = 360/3= 120

» x = 120°(one angle)

Other angle = x/2 = 120/2 = 60° .
