Answer:
71.49134 feet
Step-by-step explanation:
Side a = 112
Side b = 99
Side c = 71.49134
Angle ∠A = 80.37° = 80°22'11" = 1.40272 rad
Angle ∠B = 60.63° = 60°37'49" = 1.0582 rad
Angle ∠C = 39° = 0.68068 rad

You can use sine to solve this exercise:
The sine law indicates that in any given triangle sin(angle)=opposite side/largest side
This way sin(39º)=x/112
Now you solve for x
X=112sin(39º)
X=70.5 approx.
