Nara created to right triangles. she started with < | jkl and drew a altitude from point k to side jl. what is he measure of x to the nearest tenth centimeter. ((show work))

To solve the problem shown above you must apply the proccedure shown below:

1. The first thing you must do is to calculate the height of the triangles, as below:

 Tanα=opposite/adjacent
 Tan(30)=y/5
 y=2.88 cm

 2. Now, you can calculate "x" by applying the Pythagorean Theorem:

 a²=b+x²
 x=√(a²-b)
 x=√(12 cm)²-(2.88 cm)²
 x=11.6 cm

your question isnt in numbers?
