Bob thanks for answering my question, it still seems a tad bit confusing as i was thinking to use a quadratic expression formula. the formula you used is a rational expression correct??

1 answer

  1. No, I did it with similar triangles. Both triangles have same angles, you are given the bases of both triangles (7, 99) and the height of the smaller 6


    reread: the 99 ft is from the point on the base of the horizontal to the bottom of the clift.
