Question

Two supplementary angles are in the ratio 7:8.
Then,
the smaller angle is :
and
the greater angle is :​

Answer 1

let the common angle be x

We know that supplementary angles are 180°

So,

7x + 8x = 180°

15x = 180°

X = 180°/15

X = 12°

angles are 84° and 96°

smaller angle is 84°

greater angle is 96°
