Question

Can someone help me with number 6 please?

Answer 1

Part A: a=10

Part B: 120°

Part C: 60°

Explanation:

Part A: set 7a+50=15a-20 and solve because they are corresponding angles.

Part B: FNT is equal to the angle MNG so plug in a=10 and you get 120 so FNT=120

Part C: NTK and KTU are adjacent angles that equal 180. if you plug in a=10 into NTK you get 120. 180-120= 60.
