(data) AB = BC = x We can draw another triangle ABD with BD = x + 10 and AB = x. x = 5.774 + 0.5774 x ..

Hence a:c = 24:35 {a:b = 4:5} x 6 {b:c = 6:7} x 5 a:b = 24:30 b:c = 30:35 (To make b equal in both ratio) Hence a:b:c = 24:30:..

Let O be the observer and P be the point under observation. Therefore, OP is the 'line of sight'. OQ is a line parallel to the horizontal plane. is called the angle of depression. The point P, under observation, is at a lower level than the observer's positio..

Solved Examples - At a point 50 m from the foot of a building, the angle of elevation of the top of the building is 70 o 36 ' . Find the height of the building. BC is the building. A is the observer. AC is its distance of the building from the observer. is the angle of elevatio..

From the formula of conditional probabilities, we have Equation (2) and equation (3) are known as multiplication rules of probability for any two events A and B of the same sample spa..

The exponential function is defined as f(x) = e x . Its graph i..

The angle elevation and the angle of depressions are the angles which the line of sight makes with the horizontal. The angle of elevation of A as observed from C equals the angle of depression of C as observed from A..

The family of all subsets of any set S is called the power set of S. We denote the power set of S by P (S). If a set S is finite, say S has n elements, then the power set of S can be shown to have 2 n elemen..
