Question

help in this question of triangles...​

Answer 1

In triangles STR

ST + TR > SR - ( 1 ) sum of two side of

triangle is greater

than third side

In triangle PQT

PQ + PT >QT. (2) sum of two side of

triangle is greater

than third side

Adding (1) and (2) equation

ST + TR +PQ +PT >SR + QT

PQ + PR + ST > SR + QS + ST. ( where

PT + TR = PR.

And QS +

ST = QT)

SQ + SR > PQ + PR
