Question

Find the missing side of the triangle. A. √321 yd B. √221 yd C. 3√38 yd D. √21 yd

Answer 1

(B)
`√(221)` yards

Explanation:

Since this is a right triangle, we can use the Pythagorean Theorem to find the length of x.

The Pythagorean Theorem states that
`a^2 + b^2 = c^2`, where a and b are our legs and c is the hypotenuse.

We need to find c, and we already know a and b, so let's substitute.

`10^2 + 11^2 = c^2\\\\100+121=c^2\\\\221=c^2\\\\c=√(221)`

Hope this helped!
