Right Triangle PSR is a 5-12-13. Hence, PR=13
Right Triangle PQT= 84^2 + pq^2= 85^2 --- PQ^2=85^2-84^2
PQ^2= (85+84)(85-84)= 169
PQ=13

Hence, Triangle PQR is an isosceles triangle
since, PQ= 13 and opposite angle Q= 65degrees, similarly PR=13, hence, opposite angle R= 65degrees
180-(2*65)= 50


Ans= B
