Question

In a $\Delta ABC$, if $\angle A={53}^{\circ }$ and $\angle C={44}^{\circ }$, then the value of $\angle B$ is

• A. ${73}^{\circ }$
• B. ${83}^{\circ }$
• C. ${103}^{\circ }$
• D. ${46}^{\circ }$

Answer 1

The correct option is B ${83}^{\circ }$

In $△ABC$

$\angle A+\angle B+\angle C={180}^{\circ }{53}^{\circ }+\angle B+{44}^{\circ }={180}^{\circ }\angle B={180}^{\circ }-{97}^{\circ }\angle B={83}^{\circ }$
