Answer:

13.6

Explanation:

Remember SOH CAH TOA

We're going to use tangent = opposite / adjacent because the 11 is opposite theta (39 degrees) and x is adjacent to it.

tan (39) = 11 / x

x = 11 / tan(39)

x = 13.584 -> 13.6 (rounded to nearest tenth)

Note: Make sure your calculator is in degree mode.
