In a ˆ†ABC,  LA - LB= 33° and  LB – LC = 18° , then

ln a ˆ†ABC, AB = BC,  LB = x° and LA = (2x - 20)°. Then,  LB = ?

∆ ABC is right angled at A. If AB = 24 mm and AC = 7 mm, then BC = ?

The angles of a triangle are (3x)°, (2x - 7)° and (4x - 11)°. The value of x is :

The perimeters of two similar triangles ∆ABC and ∆PQR are 36 cm and

.  If ˆ†ABC is an isosceles triangle with  LC = 90° and AC = 5 cm, then AB = ?

Two poles of heights 6m and 11m stand vertically on a plane ground. If the

distance between their feet is 12m, what is the distance between their tops?

A ladder is placed in such a way that its foot is 15m away from a wall and

its top reaches a window 20m above the ground. The length of the ladder is :

The radius of a circle is 13 cm and AB is a chord which is at a distance of

12 cm from the centre. The length of the chord is :

A chord of length 30 cm is at a distance of 8 cm from the centre of a circle.

The radius of the circle is
