Question

find the length x of the side of the larger triangle shown in the figure at the left. assume that the two triangles are similar, and use the fact that the corresponding sides of similar triangles are proportional.

Answer 1

x= 5

Explanation:

Since both of these triangles are similar/ proportional, we can set up a proportion to solve for the missing side, x, by comparing sides of both triangles.

`(5.6)/(4) =(7)/(x)`

Cross multiply, and solve for x.

5.6x=28

x= 5
