Question

Find the missing angle(in degree) in the triangle ABC.

• A. 52

Answer 1

The correct option is A 52
Triangle ABC is a right angle triangle.
$m\angle B={90}^{\circ }$
and, $m\angle A={38}^{\circ }$


$\because m\angle A+m\angle B+m\angle C={180}^{\circ }\Rightarrow m\angle C={180}^{\circ }-(m\angle B+m\angle A)\Rightarrow m\angle C={180}^{\circ }-({90}^{\circ }+{38}^{\circ })={180}^{\circ }-{128}^{\circ }={52}^{\circ }$

So, measure of angle C = ${52}^{\circ }$ .
