State if the given angles are conterminal.
$$\alpha =185^{\circ}, \beta =-545^{\circ}$$
  • A
    True
  • B
    False

Solution

$$\alpha =185^{\circ}, \beta =-545^{\circ}$$
  Here  $$\alpha -\beta =185^{\circ}-\left ( -545 \right )^{\circ}=730^{\circ}$$
  Hence, the given angles are not coterminal.

Ans: 9
