I got 13.7 is that correct

Ghella [55]

Answer:

The answer to your question is 10.5 in

Step-by-step explanation:

Data

First triangle

height = x

base = 7 in

Second triangle

height = 12 in

base = 8 in

Process

1.- Use proportions to solve this problem, relates the sides of a triangle with the same sides of the other triangle.

$\frac{x}{7} = \frac{12}{8}$

2.- Multiply both sides by 7

$7\frac{x}{7} = \frac{7(12)}{8}$

3.- Simplify

x = $\frac{84}{8}$

4.- Result

x = 10.5 in
