Question 955424
Suppose ABC is a right triangle with sides of length a, b, and c and right angle at C. Find the exact value of the indicated trigonometric function. You may need to use the Pythagorean theorem to find the unknown side length. Rationalize the denominator if necessary. Find sec B when a=3 and b=7.
-----
sec(B) = r/a = sqrt(3^2+7^2)/3 = sqrt(58)/3
