Correct Answer - Option 4 : Neither 1 nor 2
Given:
Concept Used:
Basic concept of trigonometric ratio and identities
Calculation:
The trigonometric ratio can be measured by measuring the angles in all the system given below
In sexagesimal system, we have 1 right angle = 90°
∴ 1° = 60'
And 1' = 60"
In centasimal system, we have 1 right angle = 100g
∴ 1g = 100'
And 1' = 100"
In circular system, the unit of measurement is radian. Radian one radian is the measure of an angle Subtended at the center of a circle by an arc of length equal to the radius of the circle.
∴ Both statements are incorrect
Hence, option (4) is correct
