Answer 2

Answer:

x = 4

Step-by-step explanation:

the dimensions of the small triangle to the large triangle are increasing by multiplying by 5.

5 times 5 equals 25

3 times 5 equals 15

so 4 times 5 equals 20

then, you have to solve the equation:

20 = 3x + 8

subtract 8 from both sides

12 = 3x

divide both sides by 3

12 divided by 3 equals 4

so x = 4
