Sam built a ramp to a loading dock. The ramp has a vertical support 2 m from the base of the loading dock and 3m from the base of the ramp. If the vertical support is 1.2 m in height, what is the height of the loading dock?

Can someone please show me how to do this. I keep on getting 5 as an answer, and I know that that is not right

    If I understand your description,
    tan angle at bottom of ramp = 1.2/3.
    Then tan angle = x/5.
    Check my thinking.
