Question

what is its answer
step by step​

Answer 1

Answer:

Step-by-step explanation:

We know that the sum of all the angles in triangle ACE is 180  

∠A+∠C+∠E=180   ..(1)

We know that the sum of all the angles in triangle BDF is 180  

 ∠B+∠D+∠F=180   ..(2)

Now by adding both equations (1) and (2) we get

∠A+∠C+∠E+∠B+∠D+∠F=180    +180  

On further calculation

∠A+∠B+∠C+∠D+∠E+∠F=360  

Therefore, it is proved that ∠A+∠B+∠C+∠D+∠E+∠F=360  

Answer 2

As we can see in the figure there are two triangles ie ABC and DEF
and we know that the sum of interior angles of a triangle is 180 so
A + B+C+D+E+F =180 +180
A+B+C+D+E+F = 360degree
