Question:

An angle is $\frac{3}{7}$ times its supplementary angles. Find the angle.

Options:

54°

63°

27°

126°

Correct Answer:

54°

Explanation:

Let A and B are two angles .

A and B are supplementary angles iff

A + B = 180º

According to question ,

B = $\frac{3}{7}$A

A + $\frac{3}{7}$A = 180º

$\frac{10}{7}$A = 180º

A = 126º

The required angle is B = 180º - 126º = 54º
