Suppose that the variables x and 0 are related through the equation x = acute angle. a) Solve the equation for sin(0) and then use trigonometry and the Pythagorean Theorem to label the side lengths of the below right triangle as functions of x: 3 sin(0) and that 0 is an 3 b) Using the triangle in (a), write the following as functions of x. You may need to apply various trigonometric identities. cos(0) = tan(0) = sin(20) = csc(0) cot(0) = sec?(0) = 1
