Question

The two triangles are similar below. Find the value of x in the following: (NOT DRAWN TO SCALE)​

Answer 1

x = 2.4

Explanation:

Corresponding sides of the similar triangles are proportional:

x/(x+3) = 8/18

18x = 8(x +3) . . . . . multiply by 18(x+3)

10x = 24 . . . . . . . . subtract 8x

x = 2.4 . . . . . . . . . . divide by 10
