∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
ANSWER
Vertical shift: 6 units up
Maximum value: 9
Minimum value: 3
EXPLANATION
The given since function is

Expand and rewrite to obtain,

Or

The vertical shift is 6 units up.
The maximum value is 6+3=9.
The minimum value is -3+6=3
Your answer is 250 yards you basically just subtract the numbers it gives you from the 294....
The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
