Question

Find the length of the missing side. Leave your answer in simplest radical form. *

Answer 1

Answer:

About 14

Step-by-step explanation:

For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)

The sides that make the right angle are legs which is A and B

The other side is the hypotenuse which is C

So you set it up as

11(11) + b(b) = 18(18)

121 + b(b) = 324

324 - 121 = 203

so b(b) = 203

but 203 is b squared so you need to find the square root of 203 which is about 14.2478.

If you round that it is 14

Check

11(11) + 14(14) = 18(18)

121 + 196 = 324

317 = 324

so about
