Question

The triangles are similar. What is the value of x?

Answer 1

Answer:

The value of x is $16\ units$

Step-by-step explanation:

we know that

If two figures are similar , then the ratio of its corresponding sides is equal

In this problem

$\frac{x}{4}=\frac{12}{3}=\frac{20}{5}$

therefore

$\frac{x}{4}=4$

$x=16\ units$

Answer 2

The value of x is 16. Each side from Triangle B is multiplied by 4 to achieve the amount in Triangle A.
