Suppose ABC is a right triangle with sides a, b, and c. The right angle is at C. Use the Pythagorean theorem to find the unknown side length. Then find the values of the six trigonometric functions for angle B. Rationalize the denominators when applicable. Given that a = 8 and c = 9, find the length of side B, sinB, cosB, tanB, secB, cscB, and cotB.
