A rectangular box has dimensions of length = 6, width = 4, and height = 5. the measure of the angle formed by a diagonal of the box with the base of the box is

Remember that the box has a 90° angle. on a box each side is 90° except if it's slanted or something. So this involves sine, cosine and tangent. ever heard of Soh Cah Toa

which means Sin = opp / hyp

Cos=adj / hyper and

Tan = opp/hyp. so basically you have to find the hypotenuse which is the diagonal lime going across the box
