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. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 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
