In a right angled triangle ABC Sin A = 5/13
calculate without finding the angel A the following
a) Cos A
b) Tan A
That means the opposite side is 5 and hypotenuse is 13 because sine is opposite over hypotenuse. That means by Pythagorean theorem the adjacent side is 12. Thus, cos A =12/13 because it is adjacent over opposite. And tangent is 5/12 because tangent is opposite over adjacent.
