Use the roles to solve the expression. always solve the problem in the parentheses. which would be 360. now multiple 360 by 5. your answer will be 1,800.

This is a 30-60-90 right triangle with the shorter leg having a length of 5.

To find the length of x, we must find the length of the longer leg of the right triangle. To do that, we must multiply the shorter leg by the square root of 3.

x=5* \sqrt{3} =5 \sqrt{3}

This is the simplest radical form. Hope this helps! :)
