Question

find m∠mlk. answer attempt 1 out of 2 m∠mlk =
submit answer

Explanation:

Step1: Identify isosceles triangle

The triangle has two equal - side markings, so $\angle K=\angle M = 36^{\circ}$.

Step2: Use angle - sum property of a triangle

The sum of interior angles of a triangle is $180^{\circ}$. Let $\angle MLK=x$. Then $x + 36^{\circ}+36^{\circ}=180^{\circ}$.

Step3: Solve for $\angle MLK$

$x=180^{\circ}-(36^{\circ}+36^{\circ})=180^{\circ}-72^{\circ}=108^{\circ}$. So $m\angle MLK = 108^{\circ}$.

Answer:

$108$
