An iron ball weighing 10 pounds rests on two smooth plane-surfaced boards that are inclined at respectively 30 and 60 to the horizontal. to the nearest whole number, what is the pressure on the board from f1?

F1=9 lb.; F2= 5lb.

Step-by-step explanation:

F1 =10 lb.* Cos (30°) = 10lb.*(0,866) = 8,66 lb. ≈ 9 lb.

F2 =10 lb.* Cos (60°) = 10lb.*(0,5) = 5 lb.

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
