Question

two supplementary angles are in the ratio 11:7.find the angles....plz help me it's emergency

Answer 1

Hey!

Let one angle be 11x°.
Let the other angle be 7x°.

According to your problem, they are supplementary angles.

Hence,
11x+7x=180
=>18x=180
=>x=10

The first angle = (10×11) = 110°.
The second angle = (10×7) = 70°.

Hope this helps you!

Answer 2

let,x be included for given ratio
so,11x +7x=180
18x=180
x=10
so, one angle is 110 and another is 70
