cos(A) = a c Which rearranges to c = a cos(A) If you know the length of both sides a and b, you can solve for the tangent of either angle A or B. Using the cosine function you can solve for c, the hypotenuse. How do you know what trigonometric function to use to solve right. To find the zeros of a quadratic function, we equate the given function to 0 and solve for the values of x that satisfy the equation.
