Question

two angles AngelA and angleB are supplymentry if AngelA is decreased what change should take place in angleB so that both the angle still remain supplymentry​

Answer 1

Answer: if angle A is decreased by X

then angle B will be increased by X

Example

let A=60° and B=120°

A+B=180°

A is decreased by 10°,A=50°

let B be increased by y

A+B+y=180

50+120+y =180

y=180-170

y=10
