What is the direction in degrees that corresponds to the bearing S 48 W? Do not give any units in your answer. As usual, your answer should consist only of a number. Your answer must be between -180 and 179.

so since its -(90+48)= -138 correct?

This is the theory i have in my textbook enter image description here

When I was in high school we used this notation for bearings. The notation S 48 W is interpreted as beginning at south, then rotating 48 degrees towards the West direction. The angle in degrees, which in this context should be measured from the North direction, is thus -180 + 48 = -132 degrees.

Note: It is negative because the direction is typically measured from the North direction and clockwise. Our bearing is 132 degrees counter-clockwise from North and therefore negative.

    so looks like i am right i clarified with my teacher he said both the answers can be right but depends on the question..2012-09-18
