Question

Can somebody help please !!!!

Answer 1

Vector A is of magnitude 12 m and it makes an angle of 37 degree with Y axis

So here we can say that

$\frac{A_x}{A} = sin37$

$A_x = A sin37$

$A_x = 12 sin37$

$A_x = 7.22 m$

Similarly we have

$\frac{A_y}{A} = cos37$

$A_y = A cos37$

$A_y = 12 cos37$

$A_y = 9.58 m$

So here we have

$A_y = 9.58 m, A_x = 7.22 m$

option A is correct
