Answer:
Magnitude = 3.64 × [tex]10^6[/tex]
စ = 43.9°
Explanation:
given data
ship to travel = 1.7 × [tex]10^6[/tex] kilometers
turn = 70°
travel an additional = 2.7 × [tex]10^6[/tex] kilometers
solution
we will consider here
Px = 1.7 × [tex]10^6[/tex]
Py = 0
Qx =2.7 × [tex]10^6[/tex] cos(70)
Qy= 2.7 × [tex]10^6[/tex] sin(70)
so that
Hx = Px + Qx ............1
Hx = 2.62 × [tex]10^6[/tex]
and
Hy = Py + Qy ..........2
Hy = 2.53 × [tex]10^6[/tex]
so Magnitude = [tex]\sqrt{((2.62 \times 10^6 )^2+(2.53 \times 10^6)^2)}[/tex]
Magnitude = 3.64 ×
so direction will be
tan စ = Hy ÷ Hx ......................3
tan စ = [tex]\frac{2.53}{2.62}[/tex]
tan စ = 0.9656
စ = 43.9°
