In a right square-based pyramid, the length of the side of the square base is 5.7cm. If the angle between the triangular face and the base is 68 degrees, find:

a) height of the pyramid (which I already worked out to be 7.05cm)
b) the angle the sloping edge makes with the base ?

Included is a diagram (: (sorry its a bit blurry, but you get the gist)

Hope you can help me!
