Step-by-step explanation:

in any equilateral triangle each angle is 60

so angle c + angle d +angle e + angle f

= 60+60+60+60

= 240

Answer 2

Step-by-step explanation:

In triangle DEF :- angle D + angle E+ angle F = 180*

In triangle ABC :- angle C = 60* ( because ABC is an equilateral triangle)

so ,

angle D + angle F + angle E + angle C = 180* +60* = 240*
