Question

The triangles are similar what is the value of x

Answer 1

The larger triangle is 5x the size of the smaller triangle.
5*5=25 and 3*5=15
So I figured that would be the same for the 3x+8 side and the 4 side.
4*5=20, So you'd set 3x+8 equal to 20 and solve from there.
3x+8=20
-8 -8

`(3x=12)/(3)`
x=4
