The angle of elevation of the top of a tower from the two points ^@ P ^@ and ^@ Q ^@ at distances of ^@ a ^@ and ^@ b \space (a > b) ^@ respectively from the base and in the same straight line with it are complementary. The height of the tower is:
In the given figure, a circle is inscribed in a ^@ \triangle PQR.^@ ^@ PQ = 8 \space cm, QR = 6 \space cm, ^@ and ^@ PR = 10 \space cm.^@ What is the length of ^@QL^@ ?
The radii of two circles are ^@14 \space cm^@ and ^@18 \space cm^@ respectively. Find the radius of the circle having its area equal to the sum of the areas of the two circles.
A object is in the form of a hollow hemisphere mounted by a hollow cylinder. The diameter of the hemisphere is 16 cm and the total height of the object is 78 cm, then choose the correct inner surface area of the object.
Two coins are tossed simultaneously ^@ 900 ^@ times and it is found that two tails appeared ^@ 450 ^@ times, one tail appeared ^@ 270 ^@ times and no tails appeared ^@ 180 ^@ times.
If two coins are tossed at random, what is the probability of getting ^@ 1 \text { tail } ^@?
