Answer:

Choice B

Step-by-step explanation:

When two shapes are similar their sides are always going to be proportional. So here we will set up a proportion to solve this.

[tex]\frac{23}{40}=\frac{x}{17}[/tex]

Now we cross multiply

[tex]391=40x[/tex]

After we got an equation we solve it

[tex]x=9.775[/tex]

Since we got a decimal we will have to round it to the place they instruct for us, on this one it is 9.8 cm so it is choice b.

The required value of x is 9.8 cm. For the two similar triangles.


Two similar triangles are given. value of x to be determined.

What are Similar triangles?

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

Here, if triangles are similar then their ratio of sides is also equal.
x/23=17/40
x = 0.425*23
x = 0.425 * 23
x = 9.8 cm


Thus, The required value of x is 9.8 cm. For the two similar triangles.
