WE have,

∠B - ∠D = 60o (i)

Since, ABCD is a cyclic quadrilateral

Then,

∠B+ ∠D = 180o (ii)

Adding (i) and (ii), we get

∠B - ∠D + ∠B + ∠D = 60o + 180o

2 ∠B = 240o

∠B = 120o

Put value of ∠B in (ii), we get

120o + ∠D = 180o

∠D = 60o

Let O be the point of intersection of the diagonals BD and AC of rectangle ABCD.

Since, the diagonals of a rectangle are equal and bisect each other.

∴ OA = OB = OC = OD

Hence, O is the center of the circle through A, B, C, D.

When two cubes are joined end to end, then
Length of the cuboid = 6 + 6 = 12 cm
Breadth of the cuboid = 6 cm
Height of the cuboid = 6 cm
Total surface area of the cuboid = 2 (lb + bh + hi)
= 2(12 x6 + 6×6 + 6×12)
= 2(72 + 36 + 72) = 2(180) = 360 cm2

Let there be cone 1 and cone 2 respectively.

Let the r and R be the radii of the two right circular cones respectively.

Ratio of base radii = 3 : 5

Volume of cone = 1/3πr²h

⇒Volume of cone 1/Volume of cone 2

⇒ (1/3*πr²h)/(1/3πR²h)

⇒ (1/3*π*3²*h)/(1/3*π*5²*h)

= 3²/5²

= 9/25

= 9 : 25

So, the ratio of their volumes is 9 : 25

P(x) = x3 - 3x2 - 9x - 5

Factors of 5 = 1,5,-1,-5

p(1) = 13 - 3 x (1)2  - 9 x (1) - 5

       = 1 -3 - 9 - 5

       = 1 - 17 = - 16 ≠ 0

p(-1) = (-1)3 x 3 x (-1)2 - 9 x (-1) -5

        = -1 - 3 + 9 - 5 = -9 + 9 = 0

p(-1) =0

∴ (x+1) is a factor of p(x)

    p(x) ÷ (x+1)

    x3 - 3x2 - 9x - 5 ÷ x + 1

    = x2 - 4x - 5

x2 - 4x - 5

= x2 - 5x + 1x - 5

= x ( x - 5) + 1 ( x - 5)

= ( x - 5) ( x + 1)
