Mathematics

Find the measure of angle which is equal to its complement.

SOLUTION
Consider the required angle as ${x}^{o}$

We know that the complement can be written as ${90}^{o}-{x}^{o}$

To find the measure of an angle is equal to its complement

We get

${x}^{o}={90}^{o}-{x}^{o}$

We can also write it as

$x+x=90$

So we get

$2x=90$

By division we get

$x=\dfrac{90}{2}$

${x}^{o}={45}^{o}$

Therefore the measure of an angle which is equal to its complement is ${45}^{o}$

You're just one step away
