the length of this vector right over here, which is the opposite side, 26.03 over the length of this vector here, which is 5.21, or we could say, we could say, if we take the inverse tangent of both sides of this, that the angle is equal to the inverse tangent, or the arctangent of 26.03/5.21 and that gives us - we have the inverse tangent of 26.03/5.21 - gives us roughly 78.7 degrees.
