1.	21. One of the end points of a diameter of a circle having centre at the origin isA (3. -2). Then, the coordinates of the other end point of the diameter are..A. (-3. 2) B. (1C.D. (3.-2)22. M is the foot of perpendicular drawn from P(5, 1) to the X-axis. Then, the coordinatesA 2ě.)B.(-5. I)C' (0,-1)D.(5,0)
Answer» ans of the first question is A (-3,2) because you know two coordinates then apply mid point formula and get your answer let unknown coordinate be (x,y) now x+3/2=0 so x=-3 and -2+y/2=0 and y=2 ans of 2nd question is D txs bhai

Answer»

ans of the first question is A (-3,2) because you know two coordinates then apply mid point formula and get your answer

let unknown coordinate be (x,y) now x+3/2=0 so x=-3 and -2+y/2=0 and y=2

ans of 2nd question is D
