Problema Solution
in a right triangle, give the length of the side not given.
a=9,c=15
i need to know what side b is
Answer provided by our tutors
using the Pythagorean Theorem we know:
a^2 + b^2 = c^2
plug the values a = 9 and c = 15 into the equation:
9^2 + b^2 = 15^2
b^2 = 15^2 - 9^2
b^2 = 225 - 81
b^2 = 144
b^2 = 12^2
b = 12 (since the length of the side must be a positive number)
side b is 12.
