Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the opposite side and the adjacent side. Therefore, we should use the tangent function.
tan(x) = 19 / 35
x = tan^-1(19/35)
x = 28 degrees
Hope this helps!
