Can someone please help me???

A line from the top of a cliff to the ground passes just over the top of a pole 6.0 feet high
and meets the ground at a point 7.0 feet from the base of the pole. If the point is 99 feet
from the base of the cliff, how high is the cliff to the nearest foot?

1 answer

6:7::h:99
or
6/7=h/99
solve for h.
