give me answer to this question please​

Answer 1

Answer:

since, all the angles in the given triangles are equal and,

we know that an equilateral triangle has all the angles of 60°

so ...

Step-by-step explanation:

angle a=60

angle b=60

angle c=60

angle d=60

angle d=60

angle e=60

angle f=60

Answer 2

Answer:

360°

Step-by-step explanation:

In ∆ ABC,

∠A + ∠B + ∠C = 180°. [ Angle Sum Property]

In ∆ DEF,

∠D + ∠E + ∠F = 180°. [ Angle Sum Property]

==> ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = 180° + 180°

==> ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = 360°
