$displacement= 1000 k m$ $"displacement="1000" "km$
$α = {36.87}^{o}$ $alpha=36.87^o$

$O A = d i s p l a c e m e n t = \sqrt{800^{2} + 600^{2}}$ $O A=displacement=sqrt(800^2+600^2)$

$O A = d i s p l a c e m e n t = \sqrt{640000 + 360000}$ $O A=displacement=sqrt(640000+360000)$

$O A = d i s p l a c e m e n t = \sqrt{1000000}$ $O A=displacement=sqrt(1000000)$

$O A = 1000 k m$ $O A=1000 " "km$

$tan α = \frac{600}{800} = \frac{3}{4}$ $tan alpha=600/800=3/4$

$α = {36.87}^{o}$ $alpha=36.87^o$
