Rishu is riding in a hot air balloon. After reaching a point P, he spots a car parked at Bon the ground at an angle of depression of 30^@ . The balloon rises further by 50 metres and now he spots the same car at an angle of depression of 45^(@) and a lorry parked at B' at an angle of depression of 30^@ . (Use sqrt3 = 1.73) The measurement of Rishu facing vertically is the height. Distance is defined as the measurement of car/lorry from a point in a horizontal direction. If an imaginary line is drawn from the observation point to the top edge of the car/lorry, a triangle is formed by the vertical, horizontal and imaginary line. The height of the balloon at point P' and distance AB are related as:

Rishu is riding in a hot air balloon. After reaching a point P, he spots a car parked at Bon the ground at an angle of depression of 30^@ . The balloon rises further by 50 metres and now he spots the same car at an angle of depression of 45o and a lorry parked at B' at an angle of depression of 30^@ . (Use sqrt3 = 1.73) The measurement of Rishu facing vertically is the height. Distance is defined as the measurement of car/lorry from a point in a horizontal direction. If an imaginary line is drawn from the observation point to the top edge of the car/lorry, a triangle is formed by the vertical, horizontal and imaginary line. If the height of the balloon at point P is 'h' m and distance AB is 'x' m, then 'x' and 'h' are related as:

If A(4,-6),B(3,-2) and C(5,2) are the vertices of $ABC, then verify the fact that a median of a triangle ABC divides it into two triangles of equal areas.

A cube has the following figures drawn on its five faces. The top surface is blank. The ellipse is between the cross and the triangle. The square is on the right of the triangle. The ellipse and the square are opposite to each other. Which face is the circle on? 1. On the top 2. Opposite to ellipse 3. Opposite to triangle 4. At the bottom

Each side of an equilateral triangle subtends an angle of 60^(@) at the top of a tower hm high located at the centre of the triangle. It a is the length of each side of the triangle, then prove that 2a^(2) = 3h^(2) .
