A simple one :
An equilateral triangle has sides of length 43. A point Q is situated inside the triangle so that the
perpendicular distances from two of the sides of the triangle are 1 and 2. What is the perpendicular
distance to the third side?
alps2011 SaysA circular park of radius 80 m has four trees at points P,Q,R and S along the periphery such that the line joining points P and R intersects the line joining Q and S perpendicularly. Find PS^2+QR^2
3 tapes A, B and C are connected to an empty tank. At the beginning, only tapes A and B were opened. A fills alcohol at a rate of 4 L/min and B fills water at the rate of 2 L/min. When the tank was 50%full, tape Z, which fills alcohol was opened. If when the tank was full, it had 80% alcohol , find the concentration of alcohol in the tank, when it was 80% full.
Need a detailed explanation.
it will be 2376
