Question

Find the measure of the angle whose complement is ${89}^{\circ }$.

• A. $6^{\circ }$
• B. ${90}^{\circ }$
• C. $1^{\circ }$
• D. $5^{\circ }$

Answer 1

The correct option is C

$1^{\circ }$

Let the angle be $x^{\circ }$.

$x+{89}^{\circ }={90}^{\circ }$ [ Sum of two complementary angles is ${90}^{\circ }$]

$\Rightarrow x={90}^{\circ }-{89}^{\circ }$

$\Rightarrow x=1^{\circ }$

Required angle = $1^{\circ }$
