Answer:
We first try to convert all the trigonometry ratios into form of equal angle to apply to the formulas and identies like
2 sin theta cos theta =sin 2 theta and sin² theta +cos² theta = 1
We convert sin 75 into cos 15 we break the square part using the formulasof
a+b²=a²+b²+2ab we place the values in in the formulas and find the final solution..
