Answer:
lol i ltterally don't know what this is and im in algebra
Step-by-step explanation:
1. Angle EFC and DCF
2. All angles of a parallelogram add up to 360 so 4x-15+127=180 degrees
3. (4) 150 degrees
4. P = 45 degrees
-30 ?
Not really sure what you mean by that but, -19-11= -30 is all I know.
a=4 n=25
5a+5=n
(a+n)-4+25
a+n=29
5(4)+5=n
20+5=25
