Question

If the length of one leg of a right triangle is 8 and the hypotenuse is √113, what is the length of the other leg?A. 19B. √177C. 9D. 7

Answer 1

Okay, here we have this:

Using the Pythagorean theorem we obtain:

c²=√113²-8²

c²=113-64

c²=49

c=√49

c=7

Finally we obtain that the correct answer is the option D.
