2) If theta is a second quadrant angle and sin = 12/13, find Cos . Solution: Since the angle is in the second quadrant, x must be negative implying Cos must also be negative. Since the sin is 12/13, this means y = 12 and r = 13. Find x by using x2 + y2 = r2. x2 + 144 = 169. x2 = 25. x = 5 or -5. Take -5. Must be in second quadrant, remember?

sin(θ) = “sine theta” ... By definition, cos(15°) = 12/h so h = 12/cos(15). To finish, we need the cosine of 15 degrees which requires a calculator. This tells us cos(15°) is about .966 so. h = 12/.966 = 12.42. We now have two out of three sides. We can get y either with the …
