I keep getting this question wrong.

A radio station antenna is 34 km away, 18 north of west with respect to an origin on a map. An office building is 33 km away, 30 east of north with respect to the origin. How far is the office building with respect to the radio station antenna, and in what direction is the office building as measured from the antenna? (a) the ofce building's distance (in km) from the antenna 66.62 X Draw a careful diagram of the displacement vectors from the origin to the antenna, from the origin to the building, and from the antenna to the building. Based on the diagram, what vector expression describes the relationship between the three vectors? Think about graphical addition of vectors. Watch signs of components. km (b) the ofce building's direction (in degrees) from the antenna, measured counterclockwise from due east 2390 x Use trigonometric functions, along with the components of the vector sum, to find the angle. Check your result against your diagram. Additional Materials m Reading
