Answer: 149.5 degrees.
Solution : The graph that illustrates the given scenario is as follows :
• From the diagram above, the angel of the the plane’s resultant vector will be calculated as follows .
Tan Θ = opposite /adjacent = y/x
Θ = tan ^-1(452 /767)
= 30.5 degrees
• Take note that our angle theta is in quadrant (II)
Therefore ,
resultant vectors angle = 180 degree - 30.5 degrees
=149.5 degrees
