    take the average base and then work it like a rectangle if fact, they should just teach a generalized form of it to start with.

    if all you have is an angle, then you cant determine much else.

    trigonometry, you either need to know some trig, or some thing about special triangles.

    yes you are, and this requires either a knowledge of trig, or knowing something about a triangle that has a 60 degree angle. either way its going to get pythaggy

    its the same information, im trying to get you to consider how we can use an equilateral triangle to help us define the height and part of the base.

    do you agree that an equilateral has 3 equal angles of 60, and 3 equal sides?

    |dw:1432871987995:dw| the height splits the base in half, how do we use the pythag thrm to find the height?
