Question

The pair of figures is similar. Find X. Round to the nearest 10th if necessary.

Answer 1

9.7 rounded to 10

Explanation:

I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do
`(23)/(x) =(40)/(17)`, you would the cross multiply 23×17 and 40×X. You would then have 40X=391, so you would divide 391÷40, so X=9.7 or 10

Answer 2

x = 9.775 cm ≈ 9.8 cm

Explanation:

If traingles are similar, then corresponding sides are in proportion:

`(x)/(17)=(23)/(40)` cross multiply

`40x=(17)(23)`

`40x=391` divide both sides by 40

`x=9.775\ cm`
