Question

Find the missing values.

Answer 1

Below in bold.

Explanation:

The 2 triangles are congruent and they are both isosceles.

So m < 3 = 54 degrees. (isosceles triangle)

m < 2 = 54 degrees. (congruent triangles)

m < 1 = 180 - 2(54)

= 180 - 108

= 72 degrees. (angles in a triangle sum to 180).

m < 4 = 72 degrees. (congruent triangles),
