Question

$LN$ is the angle bisector of $\angle MLK$. Find $\angle MLN.$

• A. ${35}^o$
• B. ${25}^o$
• C. ${45}^o$
• D. none of the above

Answer 1

Answer: (B)

${25}^o$

$LN$ is the angle bisector of $\angle MLK$ . So it divides $\angle MLK$ in two equal angles; $\angle MLN$ and $\angle KLN$..

Hence $\angle MLN=\frac{\angle MLK}{2}=\frac{{50}^{\circ }}{2}={25}^{\circ }$.

Hence option $B$ is correct.
