Answer:
B&C: tan F=0.0833 & tan H=12.0000
Step-by-step explanation:
The tangent relationship is always opposite/adjacent.
When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.
1/12 is 0.0833
When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.
12/1 is 12.
