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

The measure of the angles of a triangle are in the ratio of 2 : 7: 11. Measure of angles are:

The lengths of one side of a rhombus and one of the two diagonals are 6 cm each. Find the area of the rhombus (in cm²). 

In triangle PQR, points A, B and C are taken on PQ, PR and QR respectively such that QC = AC and CR = CB. If ∠QPR = 40°, then ∠ACB is equal to: 

An angle is four times its complementary angle. What is the measure of the angle?

Ratio of the number of sides of two regular polygons is 5 : 6 and the ratio of their each interior angle is 24 : 25. Then the number of sides of these two polygons are 

The length of the common chord of two intersecting circles is 24 cm. If the diameter of the circles are 30 cm and 26 cm, then the distance between the center (in cm) is 

In the figure given below, PT=6 cm and PA=4 cm. What is the length of AB?
