The lengths of the lengths placed on the sides of a point inside an equilateral triangle are 6 cm, 8 cm and 10 cm. What is the area of the triangle?

AB is diameter of a circle with centre 'O'. CD is a chord which is equal to the radius of the circle. AC and BD are extended so that they intersect each other at point P. Then find the value of ∠ APB.

If each side of a cube is increased by 10%. Then find the percent change in the volume of the cube.

Each exterior angle of a regular polygon measures 9°. How many sides does the polygon have?

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

The largest and the second largest angles of a triangle are in the ratio of 3 : 2 respectively. The smallest angle is 20% of the sum of the rest two angles. What is the sum of the smallest and the second largest angles?

Areas of two similar triangles are 36 cm² and 100 cm². If the length of a side of the larger triangle is 20 cm, then the length of the corresponding side of the similar triangle is:

The adjacent angles on a straight line are in the ratio 5 ∶ 4, then the smaller angle is –
