I really need help... this is confusing me and I don't understand it. 30 POINTS if the answer is correct... don't just answer it because of the points. I will delete the answer and you won't get the points. PLEASE HELP Write a paragraph proof of the Triangle Angle Sum Theorem using the following figure. A line should pass through F as part of the proof.

see below

Step-by-step explanation:

we construct a parallel line to ED through F

as shown in the picture

so by angles between parallels

a=d

b=e

so what does

a+b+c equal? this is the triangle angle sum

it equals c+d+e and

the sum makes a straight angle so that's 180°

so

c+d+e=180

which is the same as

a+b+c=180

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

i got 142 as my answer
