Answer:
m<EFG =
, and m<GFH = 
Step-by-step explanation:
Linear pair angles are two supplementary angles.
Thus,
m<EFG + m<GFH = 
2n + 21 + 4n + 15 = 
collecting like terms, we have:
6n + 36 = 
6n =
- 36
6n = 
divide both both sides by 6,
n = 
Therefore,
m<EFG = 2n + 21
= 2 x
+ 21
= 48 + 21
= 
m<GFH = 4n + 15
= 4 x
+ 15
= 96 + 15
= 
Thus m<EFG =
, and m<GFH =
