Question

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

Answer 1

Answer:

$\frac{3}{6} =\frac{7}{6+x}$

Step-by-step 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.
