Let VK and KJ be perpendicular line segments, each of length 6cm. Suppose P and Q are the mid-points of VK and KJ respectively. If R is the point of intersection of VQ and PJ, then the area of triangle RQJ is
A. 6 B .3 C.3_/2 D.6_/2
in an apartment there is an elevator.The number of floors in the building including the ground floor is 21.If 10 persons enter the elevator at ground floor,what is the probability that all the 10 persons will exit the elevator at different floors?
VQ = PJ = _/45 (sq root of 6^2 +3^2)
Point R is the centeroid as PJ and VQ are medians.
medians are divided in the ratio of 2:1 by the centeroid.
so RQ = _/45/3
Connecting RK...
in triangle RKJ again RQ is the median..
Area of RKJ = 1/2*6*_/45/3 = _/45
Area of RQJ = _/45/2
