Idk what to do, I made a triangle for the problem, but when it came to angle of elevation im clueless...help?
The rim of a basketball hoop is 10ft above the ground. The free-throw line is 15 feet from the basket rim. If the eyes are of a basketball player are 6 feet above the ground, what is the angle of elevation of the players line of sight when shooting a free throw to the rim of a basket?
first off, trig functions do not stand alone. you cannot just have tan you must have tan(something). in this case, the something is x
note the modification i made to your original diagram. the broken red line is the base of the triangle we are working with. it is 6 feet off the ground, so we only go 4 more feet to hit the rim. this forms the height of our right-triangle
so you have tan(x) = 4/15 and now we continue
