u+v =8.323717394km

Ф= 64.86489406 °

Step-by-step explanation:

u=4km

v=5km

For easy calculations let's decompose the vector in its rectangular components:

$u_x=u*cos(\alpha )=4000*cos(90)=4000*0=0$

$u_y=u*sin(\alpha )=5000*sin(90)=4000*1=4000$

$v_x=v*cos(\beta )=5000*cos(45)=3535.533906$

$v_y=v*sin(\beta )=5000*sin(45)=3535.533906$

Now lets calculate the resultant vector:

u+v=R

R=R_x+R_y

R_x=u_x+v_x=0+3535.533906=3535.533906

R_x=u_y+v_y=4000+3535.533906=7535.533906

Finally let´s calculate the magnitude and direction of R:

║║= $\sqrt{(R_x)^{2}+(R_y)^{2} }=\sqrt{(3535.533906)^{2}+(7535.533906)^{2} } =8.323717394km$

Ф= $arctan(\frac{R_y}{R_x})=arctan(\frac{7535.533906}{3535.533906})=64.86489406$ °
