Question

Find FJ. This is urgent.

Answer 1

FJ = 9

Explanation:

if a line is parallel to a side of a triangle and intersects the other 2 sides, it divides those sides proportionally.

HF is parallel to IJ and intersects the other 2 sides , then

`(FJ)/(FG)` =
`(HI)/(HG)` ( substitute values )

`(FJ)/(18)` =
`(4)/(8)` ( cross- multiply )

8 FJ = 18 × 4 = 72 ( divide both sides by 8 )

FJ = 9
