Question

The triangles below are similar. 3x+3

Answer 1

x = 11

Explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

`(3x+3)/(x+7)` =
`(38)/(19)` = 2 ( multiply both sides by x + 7 )

3x + 3 = 2(x + 7)

3x + 3 = 2x + 14 ( subtract 2x from both sides )

x + 3 = 14 ( subtract 3 from both sides )

x = 11
