Q. 3

# Express each of the following angles in degrees.

(i)

(ii)

(iii)

(iv) -4

Answer :

(i) Formula : Angle in degrees =

Therefore, Angle in degrees =

(ii) Formula : Angle in degrees =

Therefore, Angle in degrees =

(iii) Formula : Angle in degrees =

The angle in minutes = Decimal of angle in radian x 60.’

The angle in seconds = Decimal of angle in minutes x 60.’’

Therefore, Angle in degrees =

Angle in minutes =

Angle in seconds =

Final angle =

( iv ) Formula : Angle in degrees =

The angle in minutes = Decimal of angle in radian x 60.’

The angle in seconds = Decimal of angle in minutes x 60.’’

Therefore, Angle in degrees =

Angle in minutes =

Angle in seconds =

Final angle =
