Triangle ABC is congruent to triangle DEF
So, DE=AB (CPCT)
DE =4.6 cm (Ans)
Now , in triangle ABC
Angle A+B+C =180degree (angle sum property of a triangle )
So, Angle c = 180-(50+60) degree
c=70 degree
A/Q , triangle ABC is congruent to triangle DEF
So, Angle F = Angle C (CPCT)
Angle F = 70 degree (Ans)
So, DE=AB (CPCT)
DE =4.6 cm (Ans)
