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

solution
here,
Let the two angle be 11x and 7x
According to the question,
11 x +7x = 180
or, 18x = 180
or , x= 180/ 18
or , x=10

And,
the 1st angle =11x (putting the value of x)
=11 × 10
= 110
the 2nd angle = 7x
= 7 × 10

=70
Therefore , the angles are 110 and 70 degree.
