Question

How to find the value of x of a triangle with all three sides having numbers.

Answer 1

20

Explanation:

When triangles are similar,

DE/DF=GH/GJ

`(x)/(16) =(15)/(12) \\\\x=(15*16)/(12) \\\\x=20`

Answer 2

x = 24

Explanation:

`(16)/(x) = (12)/(18)`

`12(x) = 18(16)`

`12x = 288`

`x = 24`
