A regular hexagon is composed of 12 congruent 30-60-90 triangles. If the length of the hypotenuse of one of those triangles is 18, find the perimeter of the hexagon.

A baseball diamond is in the shape of a square, with the distance between consecutive bases of 90 feet. The second baseman wants to make an out at home plate. How far must he throw the ball?

Triangle ABC is a 45°-45°-90° triangle with C at the right angle. If AC = 5, find BC.

In ABC, mA = 30 and mC = 90. If the length of BC is five more than one-fourth of AB, find the length of the longer leg of the triangle.

In regular hexagon ABCDEF, AB = 20. Find AD and CE.

In triangle ABC, the ratio of the measure of angle A to angle B is 1:3. The measure of angle C is half the sum of the measures of angles A and B. If AC = 8, find BC.
