Point p divides the line segment joining A(-1, 3) and B(9,8) in ratio k:1. If p lies on the line x – y + 2=0, then value of k is Given that the point (x, y) divides the line joining two points in the ration of k:1 By using the section formula, we can find the value of k x... View Article
If the two numbers are 35 and 49, find a third number such that the LCM of the three numbers is 1225 Given that, the LCM of three numbers = 1225. The two numbers are 35, 49. Let the third number be “x”. The multiples of 35... View Article
Find the point in which the graph of the linear equation 2x+3y=6 meets the x-axis. As we know the equation of a line that meets x=axis is y = 0. So, if y = 0, 2x + 3(0) = 6 2x = 6 x = 6/2 = 3 Hence, the point in... View Article
If A, B, C, D are the angles of a cyclic quadrilateral, show that cosA + cosB+ cosC+ cos D= 0 As the quadrilateral ABCD is cyclic in nature, A + C = 180° and B +D = 180° Hence, Cos A = Cos (180° - C) = -Cos C …... View Article
