An airplane is flying at a speed of 580 km/h on a bearing of North 60° east. The wind blows from a bearing of North 45° west at a speed of 60 km/h. What is the planes actual ground speed kilometers per hour? What is the planes true course? Write the true direction as an angle theta from the positive X axis.

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2
