BY SIN RULE. P/SIN = Q/SIN = R/SIN. Given equal angles THERFORE P = Q = R. |

@Chiru. Where is it mentioned of equal angles? |

If Q=R means Q-R=0, so why not option D? |

Equally inclined to each other means the angle between PQR is 180 degree. How the sine rule will work? sin180= zero. And if we use that its not defined. Can anyone explain? |

The direction is not given so we can not say that Q-R=0 so the given answer is correct. |

Angle between them is 120 because 360/3 = 120. |
