Draw and label of diagram!!!
x represents the side of the equilateral triangle also the hypotenuse of the semi-equilateral triangle
x/2 represents the "semi" side of the equilateral triangle and sides opposite the 30° angle
x2 - (x/2)2 = side opposite 60° (Pythagoras)
What is the ratio between the two short sides?
