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

`(A_x)/(A) = sin37`

`A_x = A sin37`

`A_x = 12 sin37`

`A_x = 7.22 m`

Similarly we have

`(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
