    If you draw a right angle triangle. The gradient will be the opposite over the adjacent sides of the triangle (Δy/Δx). So you will have tanx=gradient.

    so for example, the question says the angle is 25 so this means tanx25 ? Which also means the gradient is 25 ?

    Gradient would be tan25.
