Thread: Proportions

Hey! Could use a little help on how to set up this proportion. I know that the height of the tree = x but I'm not sure where 2x+4 should be put or if that is even right, here is the question:

At a point on the ground 60 ft. from the base of the tree, the distance to the top of the tree is 4 ft. more than 2 times the height of the tree. Find the height of the tree.

Any help is appreciated---just need help on setting up the proportion. Not solving all the way. Thanks.

This is easy let the hieght of the tree be x, therefore, the distance from the top of the tree to the point on the ground 60 feet away from the base of the tree ( the hypotenuse) is 2x+4. So, by the pythagorean relationship, we have



can you take it from here?

Let the height of the tree be h.

The hypoteneuse of the triangle formed is given as 2h+4. You had that right.

The height of the tree is then:



solve for h.

It is a nice integer.

By the way, this is not a proportion problem. There is no other "triangle" given for which this one is proportional to.

You know what I mean.

Thanks. I realize that now. Sorry for the confusion.

It's cool man. We live and we learn. Peace Out.
