The legs of an isosceles right triangle are 11 cm long. find the length of the hypotenuse. round to the nearest tenth if necessary.. a. 15.6 cm . b. 22 cm . c. 7.8 cm . d. 19.1 cm

 If there is a hypotenuse, the triangle is a right triangle. From the Pythagorean Theorem: 

c^2 = a^2 + b^2 [the square of the hypotenuse is the sum of the squares of the other two sides] 

c^2 = 11^2 + 11^2 = 121 + 121 = 242 

c = sqrt(242) = 15.56 cm (rounded)

The length of the hypotenuse would be :

h^2 = 2 (11)^2 

h^2 = 242

h = 

h = 15.6 cm

So the answer would be option A.

hope this helps

The correct awnser is 29.76 pounds.
