One leg of an isosceles right triangle measures 11 inches. What is the approximate length of the hypotenuse?

Answer 1

Answer: 15.5 inches

Explanation:

We’re accepting that legs = 11 inches.

hypotenuse^2 = 11^2+ 11^2 = 121+121 = 242 taking square root on both sides, hypotenuse = √242 => 11√2 or 15.5 inches.

Answer 2

since it is isosceles right triangle, both legs = 5 inches.

using pythagoras theorem,

hypotenuse^2 = 5^2 +5^2 = 25+25 = 50 taking square root on both sides, hypotenuse = sqrt 50 = 5 sqrt 2 or 7.071

rounded to nearest tenth, length of hypotenuse is 7.1 inches.
