A roller coaster moves 200 ft horizontally, then rises 135 ft at an angle of 30.0° above the horizontal. Next, it travels 135 ft at an angle of 40.0° below the horizontal. Use graphical techniques to find the roller coaster's displacement from its starting point at the end of this movement.
magnitude _____ ft
direction ______ ° (measured counterclockwise from the +x axis)
Update:magnitude 421 ft is CORRECT. Is there an equation to solve this problem?
direction ____° (measured counterclockwise from the +x axis)
the problem to the second question is wrong. Could some1 help me plz...thanks

To help visualize this problem you should draw a sketch.
The length of vector R and the angle theta can be measured to find, with use of your scale (in sketch), the magnitude and direction of the resultant displacement. The result should be: approximately 421 ft at 3 degrees below the horizontal.
