Melody, I have to go but if my answer is wrong please white it for me

OK, zegroes.....we have a right triangle......we know one side, the height of the tower which is 80 ft and we're trying to find the adjacent side, i.e., the distance the stake is from the tower.

So we have

tan 72 = opposite / adjacent

tan 72 = 80/ adjacent           multiply by "adjacent" on each side

adjacent * tan 72 = 80          divide by the tan 72 on both sides

(adjacent =   80 / tan 72 ) =   about 26 ft.

And that's how far the stake is from the tower base

I'll include a picture if you need it

I think reinout-g made a slight mistake...it should be the tan of 18 degrees, not 28 degrees
