Question

The triangles are similar.

What is the value of x?

Answer 1

x=4

Explanation:

First of all, the sides of the smaller triangle are multiplied by 5 to make it bigger. So, multiply 4 by 5 which gives you 20. So, 20= 3x+8.

Now that we have our equation, we need to isolate the variable.

Subtract 8 from both sides.

20= 3x+8

- 8 -8

Divide both sides by 3.

12= 3x

3 3

x= 4
