    TRX is a 30°-60°-90° right triangle. The hypotenuse is twice the side opposite 30° The side opposite 60° is √3 times times the side opposite 30° |dw:1435250702555:dw|

    You have the 60° side and want the 30° side. any ideas on how to get it?

    you have a 30-60-90 triangle. All 30-60-90 triangles are similar, which means all their sides have the same proportional relationships. The relationships are generally defined from the 30° side, which I used the letter "a" for in the picture. Multiply the 30° side by 2 to get they hypotenuse (that's why the hypotenuse is "2a") Multiply the 30° side by √3 to get the 60° side (the 60° side is "a√3"). Your problem gives you a 60° side and asks for the 30° side. so instead of multiplying by √3, you need to divide by it.
