Question

Find the radian

I)25°
ii ) -47°37'

Answer 1

i ) We know that

1 ° = π /180 radian

25° = π/180°

= 22/7/180°× 25

= 22 ×25/7 ×180°
= 11 × 5 /18

= 55/126 Radian

ii )
-47°30'

= π /180 × -47 1/2

= 22/7/180 × -95/2

= - 95π/360°

= -19π/72

Answer 2

here is the answer
1=55 /126
2 =19π/72
