Find the missing side of the triangle. A. 321−−−√ yd B. 221−−−√ yd C. 338−−√ yd D. 21−−√ yd

Answer:
[tex] x = \sqrt{221} yd [/tex]
Step-by-step explanation:
Use Pythagorean theorem to find x.
Thus, the sum of the square of the lengths of two legs of a right triangle equal the square of the hypotenuse, which is the longest side.
Thus,
[tex] x^2 = 11^2 + 10^2 [/tex]
[tex] x^2 = 121 + 100 [/tex]
[tex] x^2 = 221 [/tex]
[tex] x = \sqrt{221} yd [/tex]
