Find a square root that lies between 17 and 18.

sqrt(300) = 17.3205...

Step-by-step explanation:

17^2 = 289

18^2 = 324

Use any number between 289 and 324, and take its square root.

For example, sqrt(300).

answer: r there any options?

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
