Question

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

Answer 1

Answer:

$x = \sqrt{221} yd$

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,

$x^2 = 11^2 + 10^2$

$x^2 = 121 + 100$

$x^2 = 221$

$x = \sqrt{221} yd$
