In Fig. 6.16, if `x+y = w+z,` then prove that AOB is a line

In Figure,if x+y=w+z, then prove that AOB is a line Fig.

In Figure,if x+y=2+z, then prove that AOB is a line.

In the given figure, if x+y=z+w then prove that AOB is a line.

In Fig.4.97, if /_A=/_C, then prove that AOB~~COD.( FIGURE )

A line perpendicular to the axis of the parabola y^(2) = 16 x intersects the parabola in two points A and B . If AB = 32 , show that angle AOB is a right angle . Also , find the area of Delta AOB .

In Fig. 6.46, if y is five times x, find the value of z.

In Fig.6.16 IF AB||CD , then

If the 4th, 10th and 16th terms of a GP are x, y, z respectively, prove that x, y, z are in GP.

If the 4th, 10th and 16 th terms of a G.P. are x, y and z, respectively. Prove that x,y,z are G.P.

In Fig. 6.40, find the values of x, y and z.
