In which quadrant will the revolving ray lie when it makes the followi

1.	In which quadrant will the revolving ray lie when it makes the following angles.(i) 280°(ii) 390°(iii) – 400°(iv) – 1120°
Answer» (i) 280° = 3 right angles + 10° Hence, the position of the revolving ray will be the fourth quadrant. (ii) 390° = 4 right angles + 30° Hence, the position of the revolving ray will be in the first quadrant. (iii) – 400° = – 4 right angles – 40° Hence, the position of the revolving ray will be in the fourth quadrant. (iv) – 1120° = -3 x 4 right angles – 40° Therefore, the position of the revolving ray will be in the fourth quadrant.

In which quadrant will the revolving ray lie when it makes the following angles.(i) 280°(ii) 390°(iii) – 400°(iv) – 1120°

Answer»

(i) 280° = 3 right angles + 10°

Hence, the position of the revolving ray will be the fourth quadrant.

(ii) 390° = 4 right angles + 30°

Hence, the position of the revolving ray will be in the first quadrant.

(iii) – 400° = – 4 right angles – 40°

Hence, the position of the revolving ray will be in the fourth quadrant.

(iv) – 1120° = -3 x 4 right angles – 40°

Therefore, the position of the revolving ray will be in the fourth quadrant.
