Answer: 
Step-by-step explanation:
Given
The hypotenuse is 13 units
One of the lengths is 12 units
The marked angle is x
from the figure, we can write
![\Rightarrow \cos x=\dfrac{12}{13}\\\\\Rightarrow x=\cos^{-1}[\dfrac{12}{13}]\\\\\Rightarrow x=22.62^{\circ}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ccos%20x%3D%5Cdfrac%7B12%7D%7B13%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Ccos%5E%7B-1%7D%5B%5Cdfrac%7B12%7D%7B13%7D%5D%5C%5C%5C%5C%5CRightarrow%20x%3D22.62%5E%7B%5Ccirc%7D)
