Question

For a triangle, m<1 =75 and m<3 =40 what does m<2 =?​

Answer 1

m<2 = 65

Explanation:

The measures of angles 1 and 3 should be added together resulting in 115 degrees, and all triangles equal 180 degrees. Therefore, to find m<2, you have to subtract 115 from 180 resulting in a measure of 65 degrees.
