A ship is 130 m away from the centre of a barrier that measures 180 m from end to end.
What is the minimum angle that the boat must be turned to avoid hitting the barrier?
~~~~~~~~~~~~~~~~~~~~~~
The barrier is a circular shape.
The minimum angle is defined by the tangent line to the barrier.
The angle is sin(a) = = = 0.69231
a = arcsin(0.69231) = 0.7647 radians, or 43.9 degrees (approximately). ANSWER
