CCSS SENSEA boat is traveling west
to cross a river that is 190 meters wide. Because of
the current, the boat lands at point Q, which is 59
meters from its original destination point P. Write an
inverse trigonometric function that can be used to
find , the angle at which the boat veered south of
the horizontal line. Then find the measure of the
angle to the nearest tenth.
