Webb11 juli 2012 · Clearly theta is part of a 3-4-5 triangle, which means that cos (theta) = 4/5. These can all be solved by employing a set of trigonometric identities known as the sum and difference formulae, which tell you how to compute the sine or cosine of the *sum* (or difference) of two angles. Are you familiar with these identities? Jul 8, 2012 #4 Villyer WebbSolve your math problems using our free math solver with step-by-step solutions.
