Question

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

Answer 1

Answer:

x = 9.775 cm ≈ 9.8 cm

Step-by-step explanation:

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

$\dfrac{x}{17}=\dfrac{23}{40}$              cross multiply

$40x=(17)(23)$

$40x=391$        divide both sides by 40

$x=9.775\ cm$

Answer 2

Answer:

9.7 rounded to 10

Step-by-step explanation:

I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do $\frac{23}{x} =\frac{40}{17}$, 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
