Question

Find the angle which is equal to twice it's complement

Answer 1

Let The smaller angle be x

so,

    x+2x = 90° [complementary angles are equal to 90°]

    3x = 90°

     x = $\frac{90}{3}$

     x = 30°

Now, the smaller angle = x = 30°

Larger angle = 2x = 2$*$30°

                     = 60°

Here it is, the larger angle is twice the smaller one.
