Question

PLEASE HELP on polygon questions!!!! Medal and Fan will be given!!!!

Answer 1

IN a parallellogram the diagonals bisect each other
so y=3x
y+12 = 6x
Solving the above x=4, y =12

Answer 2

yes 1 is indeed (3m + 20)
sum of internal angles in a parallellogram is 360 degrees
so (3m+20) + 5m + (3m+20) + 5m =360
you can also use sum o fadjacent angles in a paralleogram is 180 to find m
3m+ 20 +5m =180
you get m = 20
hence angle 1 is 3m +20 which is 80 degrees

Answer 3

Oh my gosh!! Thank you SO MUCH!! And thanks for breaking it down!! Like, I just don't think my teacher gives a 2 cent turn about us, and she woun't help. lol THANK YOU!
