I have a triangle, one corner, the smallest of the three, is 30 degrees. Another angle is 90 degrees, making the other one 60 degrees. The odd side, the one opposite of the right angle, is 15 m. I need to find the other two lengths. What do you guys think? How would you get your answer?

my high school freshman son is trying to finish his homework and this one is throwing us. We know the equation of M=DxV, but how do you figure out the mass and volume of your own body? Do you think it's possible to figure this out or is it a trick question? Or maybe we're very bad at math. Anyway, we would really appreciate a serious answer. Thanks!

2a. Consider a hand holding a ball at rest. The ball weighs 10 N. The forces acting on the ball are its weight and the force of the hand on the ball. The forces acting on the hand are the weight of the hand and the force exerted by the ball on the hand.

How big is the reaction force associated with the weight of the ball? What object is responsible for that force?

How big is the force that the ball exerts on the hand? How big is the reaction force associated with this force?

Now let the hand exert a 15 N force on the ball.

How big is the reaction force associated with the weight of the ball? What object is responsible for that force?

How big is the force that the ball exerts on the hand? How big is the reaction force associated with this force?
