Question

This is for a Geometry-H class. Please help.

Answer 1

`m\angle EFG=161^(\circ), m \angle LMN=19^(\circ)`

Explanation:

Supplementary angles add to 180 degrees, so:

`3x+17+(1)/(2)x-5=180 \\ \\ 6x+34+x-10=360 \\ 7x+24=360 \\ \\ 7x=336 \\ \\ x=48 \\ \\ \implies m\angle EFG=161^(\circ), m \angle LMN=19^(\circ)`
