    |dw:1365551726121:dw| adj = 5 angle = 6 tan(angle) = opp/adj You want to find the length (height) of the opposite side: So if tan(6) = opp/5 then opp = tan(6) * 5

    She's looking for the height, not the area.

    She doesn't have the height yet. She's looking for the height. The height is the length of the opposite side. That's what she's looking for. The length of the opposite side. The length of the opposite side = the height. The height is equal to tan(6) * 5

    open a calculator and find the value of tan(6), then the result should be multiplied by 5
