The 636 N weight held by two cables. The left-hand cable had tension 840 N and makes an angle of θ with the wall. The right-hand cable had tension 890 N and makes an angle of θ1 with the ceiling.
a) What is the angle θ1 which the right-hand cable makes with respect to the ceiling?
b) What is the angle θ which the left-hand cable makes with respect to the wall?
