To find x you can use cosine since you know the adjacent side and the hypotenuse. Remember that for cosine it is adjacent over hypotenuse
cos(x) = [tex]\frac{28}{72}[/tex]
cos(x) = [tex]\frac{7}{18}[/tex]
To find the x we must take the inverse of cosine:
[tex]cos^{-1}[/tex]([tex]\frac{7}{18}[/tex] = x
x = 67.1146...
x ≈ 67.1 degrees
