Question

The complementary angle of 37.4° isdegrees.

Answer 1

We know complementary angles are those angles which add up to ${90}^o.$

Here, one angle is ${37.4}^o$.
Let its complement angle be $x.$

Now, ${37.4}^o+x={90}^o$
$\Rightarrow x={90}^o-{37.4}^o$
$\Rightarrow x={52.6}^o$

Hence, correct answer is ${52.6}^o.$
