Sakshi · Answer

So let the triangle of sides ab, bc and ac, where ac is the hypotenuse of side 4x and the opposite perpendicular side ab is x . Let the angle you needs to find is y. Sin(y) = opposite / hypotenuse = x / 4x = 1/4 ............ y = sin^-1 ( 1/4 ) which is approximately equal to 75 and 15 . Since, it`s an acuteness angle the answer is 15
