Given that P 12, Q = 5 and R = 13 also P+Q=R, then the angle between P and Q will be

Given that P 12, Q = 5 and R = 13 also P+Q=R, then the angle between P and Q will be

If P+Q=R and |P|=|Q|= sqrt(3) and |R| ==3 , then the angle between P and Q is

If P+Q=R and |P|=|Q|= sqrt(3) and |R| ==3 , then the angle between P and Q is
