Question
Which of the following is the advantage of zero
tillage?Solution
Zero tillage helps in controlling soil erosion by leaving the soil undisturbed, retaining crop residues on the surface to protect against wind and water erosion.
An angle is equal to 3/7 of its supplement. The angle is :
At the centre of a circle of 20 cm radius, the angle made by an arc of 24(4/9) cm length is
ABC is a triangle. AB = 5 cm, AC = √41 cm and BC = 8 cm. AD is perpendicular to BC. What is the area (in cm2) of triangle ABD?
