1.	tary angios are in the ratio 2:7. Find the tmeazures ofangles.
Answer» Let one of the angles be x° and the other supplementary angle be (180 - x)°. It has been given that these two angles are supplementary and are in the ratio 2:7. ∴x/(180-x)=2/7=>7x=2(180-x)=>9x=360=>x=40 ∴the two angles are X equals to 40° and the other angle equals to (180°- x) equals to (180°-40°) equals to 140°.

Answer»

Let one of the angles be x° and the other supplementary angle be (180 - x)°.

It has been given that these two angles are supplementary and are in the ratio 2:7.

∴x/(180-x)=2/7=>7x=2(180-x)=>9x=360=>x=40

∴the two angles are X equals to 40° and the other angle equals to (180°- x) equals to (180°-40°) equals to 140°.
