Solution

we can construct a triangle when two sides and the angle between them are given.
Here, two sides $P Q = 7.2 c m,$ $P R = 5.7 c m$ are given and the angle between these two sides is $∠ P$ which is not given.
Hence, We $c a n n o t$ construct a triangle $∆ P Q R$ when $P Q = 7.2 c m,$ $m ∠ R = 60^{o}$ and $P R = 5.7 c m$
