The 306090 triangle with hypotenuse of length 2 units has the other two sides of length 1 unit and √3 units, with the side of length 1 unit opposite the 30 degree angle. Thus if you have a 306090 triangle with one side of length 73 units and you know which side it is you can use similar triangles to find the lengths of the other two sides. Penny
