Answer:
The value of x is 15. The measure of angle L and K is 45.7 degree. The measure of angle M is 77.6 degree.
Step-by-step explanation:
It is given that
Since two angles are congruent, therefore we can say that the triangle KLM is isosceles triangle.
The sides KM and LM are congruent.
The value of x is 15.
The length of side KL is
The length of side KM and LM is
Therefore length of sides are 68, 68 and 95.
Use Law of cosine to find the measure of each angle.
Apply this formula according to the angle.
Therefore the measure of angle L and K is 45.7 degree.
The measure of M is calculated as,
Therefore the measure of angle M is 77.6 degree.
