1. The problem statement, all variables and given/known data Q)A circle C whose radius is 1 unit touches the x-axis at 'A'.The centre Q lies in 1st quadrant.The tangent(other than x-axis) from origin touches the circle at T and a point P lies on it such that OAP is a right angled triangle with right angle at 'A' and its perimeter is 8 units.Then the length of QP is:- a)0.5 b)4/3 c)5/3 d)None of these 2. Relevant equations 3. The attempt at a solution This seems to difficult to me as nothing is given except the radius of the circle. Suppose I assume the point T to be (α,β) I can write the equation of tangent in terms of α and β if only I know the equation of the circle.
