Answer:
M<GEF=30
M<DEF=40
Step-by-step explanation:
First you want to solve for x. to do that you put both of the equations together and make it equal to 70 since M<GED=70. so you would get 2x+10+5x-10=70.
when you solve that you get x=10. next you substitute x with 10 in the other equations to solve for the unknown measure angle. So M<GEF=2(10)+10 and M<DEF=5(10)-10. When you solve that you get M<GEF=30 and M<DEF=40. you can check this by adding them together and they add up to 70 which is the M<=GED.
