Problem

Right triangles start box, 1, end box, start box, 2, end box, and start box, 3, end box are given with all their angle measures and approximate side lengths.
Three triangles labeled one, two, and three. The triangle labeled one has its short leg labeled three point four units. Its long leg is nine point four units. Its hypotenuse is ten units. The angle opposite of the hypotenuse is ninety degrees. The angle opposite of the short leg is twenty degrees. The angle opposite of the long leg is seventy degrees. The triangle labeled two has its short leg labeled five point seven units. Its long leg is eight point two units. Its hypotenuse is ten units. The angle opposite of the hypotenuse is ninety degrees. The angle opposite of the short leg is thirty-five degrees. The angle opposite of the long leg is fifty-five degrees. The triangle labeled three has its short leg labeled six point four units. Its long leg is seven point seven units. Its hypotenuse is ten units. The angle opposite of the hypotenuse is ninety degrees. The angle opposite of the short leg is forty degrees. The angle opposite of the long leg is fifty degrees.
Use one of the triangles to approximate the ratio start fraction, W, Y, divided by, W, X, end fraction.
