Question

two suplymentary angles differ by 42, find the the angles?​

Answer 1

Answer:

111°, 69°

Step-by-step explanation:

Let one of the angles be x°, the other angle will be (180°-x) as they are supplementary.

Given, their difference is 42°.

⇒ x°- (180°-x) = 42°

   2x°- 180° = 42°

   2x°= 42°+ 180°

   2x°= 222°

    x°= 111°

∴ The angles are x= 111° and (x- 180°)= 69°

Answer 2

Answer:

y=69,x=111

Step-by-step explanation:

let the 2suplymentry angle be X&Y

X+Y=180

X-Y=42

X+Y=180

-

X-Y=42

Y=69

X=180-Y =111
