Step-by-step explanation:
Refer the attached figure
Components of vector :

We are supposed to find What angle does this vector make with the positive x axis

Now ,

So, this vector make an angle of 141° with the positive x axis
Find MA:
MA = 67.2-32 = 35.2
Now set up a ratio:
35.2/67.2 = x/81.9
Cross multiply:
67.2x = 2882.88
Divide both sides by 67.2:
X = 42.9
