Answer 1

SoIution :

1) Convert 345° into radians :

We know :

⇔ 1° = (π/180) radians

⇒ 345° = (345π/180) radians

⇒ 345° = (23π/12) radians

∴ Correct option : 2) 23π/12

---------------------------------------------------------

2) Convert 150° into radians :

⇔ 1° = (π/180) radians

⇒ 150° = (150π/180) radians

⇒ 150° = (5π/6) radians

∴ Correct option : 4) 5π/6

----------------------------------------------------------

3) Convert -945° into radians :

↔ 1° = (π/180) radians

⇒ -945° = (-945π/180) radians

⇒ -945° = (-21π/4) radians

∴ Correct option : 2) -21π/4

------------------------------------------------------

4) Convert (π/18) radians into degrees :

⇔ 1 radian = (180/π)°

⇒ (π/18) radians = (180π/18π)°

⇒ (π/18) radians = 10°

∴ Correct option : 3) 10°

-------------------------------------------------------------------

5) Convert (107π/36) radians into degrees :

⇔ 1 radian = (180/π)°

⇒ (107π/36) radians = [(180 × 107π)/36π]°

⇒ (107π/36) radians = (19260/36)°

⇒ (107π/36) radians = 535°

∴ Correct option : 2) 535°
