Answer:
a=9.641, b=11.49
Vector will be 9.641 i + 11.49 j
Step-by-step explanation:
We have given that vector V has the magnitude of 15
And it makes an angle of 50
with positive x axis
Now let the x component of vector V is a and y component of vector V is b
So 

In vector form 9.641 i+11.49 j
Replace x with the x value solve to get the y value.
