Question

Find X to the nearest tenth

A 14.4
B 4.8
C 1.7
D 9.4

Answer 1

Explanation:

The 2 smaller triangles are proportionate to one another because they are 2 parts of the same larger triangle. Setting up the proportion, one triangle at a time:

`(x)/(8.3) =(11.6)/(6.7)` and cross multiply to get

6.7x = 96.28 so

x = 14.37 or 14.4, choice A.
