In this case, we are given the two legs of a right triangle, 15 cm and 25 cm, and we are asked to solve for the length of the hypotenuse.
Using the Pythagorean Theorem, which states that a^2 + b^2 = c^2, we can plug in the given values:
(15)^2 + b^2 = (25)^2
225 + b^2 = 625
b^2 = 625 - 225
b^2 = 400
Taking the square root of both sides to solve for b:
b = √400
b = 20
Therefore, the length of side b is 20 cm.
Use the Pythagorean Theorem to solve for b round to two decimal places if needed
