Question

I need some help with this problems please solve 33

Answer 1

33.

We have an isosceles triangle, which means that two of the sides of the triangle are equals, the same is with the angles

side LM= side MN

angle L =angle N

Also we need to remember that the sum of the interior angles of a triangles is 180°

angle M=120

angle N=x

angle L=x

120+x+x=180

2x=180-120

2x=60

x=60/2

x=30

m < M =120°

m< N=30°
