Answer:
11.49
Explanation:
a^2+b^2=c^2
think of this as a triangle, we are going to use Pythagorean theorem.
the hypotenus is 14 ft and one of the legs is 8 ft. so the other leg is x
8^2 + x^2 = 14^2
64 + x^2 = 196
subtract the 64 on both sides
x^2 = 132
to counter the square we square root it
so x = the square root of 132 which comes out to a decimal
11.489....
rounded it would be 11.49
hope this helped
