The length of a tangent from a point A at a distance 5 cms. from the centre of the circle is 4 cms. Radius of the circle is

If in a ΔABC, AD is internal angle bisector & D is a point on BC, AB = 9 cm, BC = 12 cm then what is BD:CD?

If G is the centroid and AD, BE, CF are three medians of ∆ABC with area 60 cm² , then the area of ∆EFG is?

Let two chords AB and AC of the larger circle touch the smaller circle having same centre at X and Y. Then XY = ?

The measure of an angle is one-third of its supplementary angle. Find its measure.

In the given figure CD is parallel to AB then ∠y is?

In ∆ABC, AB = 5cm, BC = 6cm and AC = 10cm then find out the value of cos A?

If G is the centroid and AD, BE, CF are three medians of ∆ABC with area 42 cm ² , then the area of ∆BGD is?
