Question

180 degree is equal to ________grade?

Answer 1

These considerations outweigh the convenient divisibility of the number 360. One complete turn (360°) is equalto 2π radians, so 180° is equal to π radians, or equivalently, the degree is a mathematical constant: 1° = ​π⁄180.

Answer 2

Find the co-ordinates of the point which divides the line segment joining the points (5,-2) and (9,6) internally and externally in the ratio of 3:1.
