In this problem, we're given an angle and two sides. Therefore, we should use a trigonometric function to solve for x.
Remember! SOH-CAH-TOA
We are given a 26 degree angle, looking from which we have the adjacent side and the hypotenuse. As such, we should use the cosine function.
cos(26) = x / 69
x = cos(26) * 69
x = 62.0168
x = 62.0
Hope this helps!
