The largest and the smallest angles of a triangle are in the ratio of 3:1 respectively. The second largest angle of the triangle is equal to 56°. What is the value of largest angle of the triangle?

If the circumradius of an equilateral triangle ABC be 8 cm, then the height of the triangle is 

If ∆ABC is an isosceles triangle with ∠C = 90° and AC = 5 cm then AB is : 

The diagonals AC and BD of a cyclic quadrilateral ABCD intersect each other at the point P. Then, it is always true that 

G is the centroid of ΔABC. The medians AD and BE intersect at right angles. If the lengths of AD and BE are 9 cm and 12 cm respectively; then the length of AB (in cm) is?

The distance between the center of two equal circles each of radius 3 cm, is 10 cm. The length of a transverse common tangent is 

In triangle ABC a straight line parallel to BC intersects AB and AC at D and E respectively. If AB = 2AD then DE : BC is

(2x + 4) and (x - 1) are the angle pairs of angles of measurement, then their measurement will be
