pair of figures is similar, fund x round to the nearest tenth if necessary possible answers34 cm21.9 cm9.8 cm29.6 cm

Answer 1

In this question, we are meant to get the value of x, in the similar figures.

Here, we need to use the formula:

`\begin{gathered} (23)/(40)\text{ = }(x)/(17) \\ \text{cross}-\text{ multiply, we have:} \\ 23\text{ x 17 = 40 x X} \\ \text{Divide both sides by 40, we have:} \\ X\text{ = }\frac{23X\text{ 17}}{40} \\ X\text{ = }(391)/(40) \\ X\text{ =9.775 cm} \\ X\text{ = 9.8 cm }\ldots\ldots OPTION\text{ C} \end{gathered}`
