Question

Two supplementary angels are in ratio 3:7.Find the two angles

Answer 1

Sum of supplementary angles = 180
Lets take ratio in x form
3x + 7x =180
10x = 180
X = 180÷ 10
X = 10
Therefore
3x = 3×18 = 54
7x = 7*18 =126

Answer 2

Hi friend,
Its ur answer.



Note that the sum of supplementary angles is 180°.

It is given that the ratio of two angles is 3:7.

Let the common ratio be x.
Therefore,
One angle = 3x
Other angle = 7x.


Sum of two angles = 180°.

So, 3x + 7x = 180°
10x = 180°
x = 18°


Therefore, 
3x = 3 X 18 = 54°
7x = 7 X 18 = 126°


Therefore,  the two angles are 54° and 126°.
