Question

Find the angle which is double its complement.

Answer 1

Finding the value of x:

We know that when the measurements of two angles sum up to ${90}^{\circ }$, they are said to be complementary angles.

Let the measure of angle be $x^{\circ }$.
As per the question:
$x=2(90-x)$
$x=180-2x$
$3x=180$
$x=60$

Therefore, the value of x is ${60}^o$.
Hence, the angle which is double its complement is ${60}^{\circ }$.
