Sickle cell anaemia is due to

In figure, and then the area of the shaded region in square units is

In the figure, and ar The value of ?

The median AD of the triangle ABC is bisected at E and BE meets AC at F. If AF:AC =1/k then the value k

In the figure, If AB = 6 cm, BE = 4cm, CD = 10cm, then EF + EC = ... Cm.

In the figure, , AB = 9cm, AD = 7cm, CD = 8cm and CE = 10cm Then DE = ?

In the figure, If AB = 3cm, PB = 2cm and PR = 6cm then QR = ? cm.

In the figure, and If OA = 3x – 1, OB = 2x + 1, OC = 5x – 3, OD = 6x – 5 then AC =....units.

Hence AC=12

Two line segments and intersect at E such that If AE = 4cm, BE = 3cm, CE=6cm and DE = x cm then x = ?

Hence x=2

In the figure, AB = BC = CD = DE = EF and AF = AE Then = ?

In the figure, AB = AC, and Then

Hence BC=CD

In the figure, ‘x° ’ and ‘y° ’ are two exterior angle measures of DABC Then x° + y° =

Hence x+y>180^o

In then

The vectors are mutually perpendicular then

If be the three vectors such that then

If then
