Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore, Angle in radians = 36 x \(\frac{\pi}{180}\) = \(\frac{\pi}{5}\)

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore, Angles in radians = 120 x \(\frac{\pi}{180}\) = \(\frac{2\pi}{3}\)

(i) Formula : Angle in degrees = Angle in degrees × \(\frac{\pi}{180}\)

Therefore, Angle in degrees = \(\frac{5\pi}{12}\) x \(\frac{180}{\pi}\) = 75°

(ii) Formula : Angle in degrees = Angle in radians x \(\frac{180}{\pi}\)

Therefore, Angle in degrees = - \(\frac{18\pi}{5}\) x \(\frac{180}{\pi}\) = - 648°

(iii) Formula : Angle in degrees = Angle in degrees × \(\frac{180}{\pi}\)

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 = \(\frac{5}{6}\) x \(\frac{180}{\pi}\) = \(\frac{150}{\frac{22}7}\) = 47.7272°

Angle in minutes = 0.7272 x 60' = 43.632'

Angle in seconds = 0.632 x 60" = 37.92"

Final angle = 47° 43' 38"

(iv) Formula : Angle in degrees = Angle in radians x \(\frac{180}{\pi}\)

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 = - 4 x \(\frac{180}{\pi}\) = - \(\frac{150}{\frac{22}7}\) = - 229.0909°

Angle in minutes = 0.0909 x 60' = 5.4545'

Angle in seconds = 0.4545 x 60" = 27.27"

Final angle = - 229° 5' 27"

D=\({180}\over{\pi}\)*R 

where D is angle in degree and R is angle in radians

(i)5\({\pi}\over12\)=\({180}\over{\pi}\)*5\({\pi}\over12\)=15*5=75º

(ii)-18\({\pi}\over5\)=\({180}\over{\pi}\)*(-18\({\pi}\over5\))=-648º

(iii)5/5=i radian=180/\(\pi\)º

(iv)-4=\({180}\over{\pi}\)*4=720/\(\pi\)º

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore. Angle in radian = 400 x \(\frac{\pi}{180}\) = \(\frac{20\pi}{9}\)

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore. Angle in radian = 225 x \(\frac{\pi}{180}\) = \(\frac{5\pi}{4}\)

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore. Angle in radian = 330 x \(\frac{\pi}{180}\) = \(\frac{11\pi}{6}\)

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

The Angle in radians = \(\frac{Angle\, in\,minutes}{60}\)

Therefore, the total angle = - (22 + \(\frac{30}{60}\)) = - 22.5

Therefore. Angle in radians = - 22.5 x \(\frac{\pi}{180}\) = - \(\frac{\pi}{8}\)

: Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Angle in radians = \(\frac{Angle\,in \,minutes}{60}\)

Therefore, the total angle = 7 + \(\frac{30}{60}\) = 7.5

Therefore. Angle in radians = 7.5 x \(\frac{\pi}{180}\) = \(\frac{\pi}{24}\)

                                   2\(\pi\)=360° and 60'=1°

                                  ⇒1'=1/60º

        7º30'=15/2º=(15/2)*(\(\pi\)/180)=0.130rad

Formula : Angle in radians = Angle in degrees × \(\frac{\pi}{180}\)

Therefore. Angle in radian = - 270 x \(\frac{\pi}{180}\) = - \(\frac{3\pi}{2}\)

Correct Answer is: (a) Monsoon

If the sum of any two angles is 180°, then the angles are called as supplementary angles.

Supplementary angle of a° is (180 – a)°

If the sum of any two angles is 180°, then the angles are called as supplementary angles.

Supplementary angle of 97° is (180 – 97) = 83°

If the sum of any two angles is 180°, then the angles are called as supplementary angles.

Supplementary angle of 13° is (180 – 13) = 167°

(i) Given angle is 20°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 20° = 70°

(ii) Given angle is 35°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 35° = 55°

(iii) Given angle is 90°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 90° = 0°

(iv) Given angle is 77°

Since the sum of an angle and its compliment is 90 

Therefore, its compliment will be:

90° – 77° = 13°

(v) Given angle is 30°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 30° = 60°

Correct option is A) 60°

Ratio of the distance covered by Akilan to that of Selvi = 10 km : 6 km

= 10/6

= 5/3

= 5 : 3

In 1 hour (60 minutes), distance covered = 6 km

In 1 minute, distance covered

= 6km/60min = 6000m/60

= 100 m

In 20 minutes, distance covered = 20 × 100 m = 2000 m = 2 km

Correct answers given by Kaarmugilan and Kavitha are in the ratio 10 : 11

Total of 84 points will be divided into 10 + 11 = 21 equal parts

Points scored by Kavitha = 11/21×84 = 44 points

Kavitha scored 44 points in the quiz.

Stone tools have been found from many sites. They are often different from the Paleolithic tools and are called ‘Neolithic’. There were tools that were polished so as to give a fine cutting edge. Mortars and pestles were used for grinding grain and other plant produce. However, Paleolithic tools were still used for some purposes. Some tools were also made of bone.

C) modern stone age

Answer is (B) stone
