Question

A vector of magnitude 10 has its rectangular components as 8 and 6 along x and y respectively. Find the angles it make with these axes.

Answer 1

10 cosa = 8

cos a= 4/5

a= 37

So it makes an angle 37 degree with x

And (90-37)= 53 degree with y

Answer 2

Answer:

→ 10 cosa = 8  

→ cos a= 4/5  

→ a= 37  

Tt makes an angle = 37 degree with x  

→ And (90-37)= 53 degree with y
