1.In a polar axis co-ordinates system, if one point lie at a distance of 3
units from origin subtending an angle 'x' with the origin and another point
is at exactly 55 degrees more than the first, find out the distance between
the two points and also the angle subtended by the second ,in radians ?
2.If a point in a particular co-ordinate system is (2, 9) and in another
co-ordinate system is (-8, 81) then by how many degrees should the first
co-ordinate system axis be rotated to get the send co-ordinate axis?
3.Given a container has a capacity V and a liquid is filled up to 1/3 of its
capacity. Another container has capacity W and a liquid is filled up to 1/7
of its capacity. If both these are mixed and poured into another container
whose capacity is X. Find out the fraction of occupation in the last
container.
答案會是(7V+3W)/21X嗎?
