```							The answer is b. Then shortcut to solving it is that we need to substitute value of theta as 30 degree.Find the realtions of values of x,y,z. You will get x/2 = y√3/2 = z√3. Find all the terms in terms of x. Substitute in the given expression, find the answer and see which one of the options matches your answer. You will get the 4 marks very easily this way.
