Nara created two right triangles. She started with LJKL and drew and altitude from point K to side JL. The diagram below shows LJKL and some of its measurements, in centimeters.

Based on the information in the diagram (below), what is the measure of x to the nearest tenth of a centimeter?

A 30 60 90 triangle has sides in the proportions of 1, square root of 3, and 2
So if JL = 5 cm then JK = 5*(2* sq root (3)) and KL = (5 / sq root (3))
