Question

What is the measure of complementary angle of 83°?Select the correct alternative from the given alternatives.
(1) 7°
(2) 17°
(3) 27°

Answer 1

We know, sum of two complementary angles is 90° always,



So, sum of 83° and its complementary angle will equal to 90°




83° + complementary angle = 90°

Complementary angle of 83° = 90° - 83°



$\boxed{ \bold{ complementary \: angle \: of \: 83 \degree \: is \: 7 \degree}}$

Answer 2

Option ( 1 ) is correct.

Explanation :

*******************************************

Two angles are said to be

complementary if their sum is 90°

***************************************

Here ,

one angle( x ) = 83°

Let second angle = y

x + y = 90°

=> y = 90° - x

=> y = 90° - 83°

=> y = 7°

Therefore

Complementary angle of 83° = y = 7°
