Torque Vectors Question (HELP)

I was given this info
r=1.5 m
d=3 m
F= 50 N
angle= 110 degrees

1. What torque is applied?
T=Fsin
T= (1.5)(50)sin(110)
T=70 J

2. At what angle would enough force be applied to achieve maximum toque?
T=Fsin
T= (1.5)(50)sin(90)
T=75 (joules)

3. If someone continues to push with a force of 50 N, what maximum torque could be applied?
T=Fsin
T= (1.5)(50)sin(10)
T=13.0 J

Are these solutions to the questions correct, if not; what do i need to change to get the correct solution?
