Question

Set up a proportion and use it to solve for x.
4
3
х
6

Answer 1

`(3)/(6) =(7)/(6+x)`

Explanation:

There are two similar triangles in this figure. The small one has a base of 6 and a height of 3.

The bigger triangle has the smaller one included in it, so you must add together the bases, 6 and x, and the heights, 3 and 4, to get the proportion.
