A helicopter takes off over level ground, first rising vertically to a height of 108 m, then flying a straight-line distance of 212 m at an angle of 36.5 degrees above horizontal.

Part A. What is the height of the helicopter at the end of these two displacements (in meters)?

Part B. If the sun is shining straight down (so that the shadow of the helicopter is always vertically below the helicopter), then what is the distance between helicopter's shadow and the takeoff point at the end of the two displacements (in meters)?
