a brace for a shelf has the shape of a right triangle. its hypotenuse is 8 inches long and the two legs are equal in length. how long are the legs of the triangle?
Answer provided by our tutors
let
a = the length of each leg, a>0
c = 8 in the length of the hypotenuse
using the Pythagorean Theorem we know:
a^2 + a^2 = c^2
2a^2 = c^2
2a^2 = 8^2
by solving we find:
a = 5.66 in approximately
