Mark the correct alternative in the following:
If D, G and R denote respectively the number of degrees, grades and radians in an angle, then
Let θ be the angle which is measure in degree, radian and grade
We know that 90°=1 right angle
right angle
right angles
right angle ……(1)
Also we know that ,π radians=2 right angles
right angle
right angles
right angles ……(2)
Also we know that, 100 grades=1 right angle
⇒1 grade right angle
⇒G grade right angles
right angles ……(3)
From (1),(2) and (3)
