@jigglypuff314 Help Please lol
jigglypuff314 (jigglypuff314):
supplementary means adds up to 180 degrees
then angle 1 and angle 2 are next to each other so they are consecutive angles
OpenStudy (anonymous):
So it would be choice B?

And All interior angles of a parallelogram add up to 180 right?
jigglypuff314 (jigglypuff314):
nope
sum of interior angles = (n-2)180 when n=number of sides
OpenStudy (anonymous):
Oh I get it now, thanks
OpenStudy (anonymous):
I need help with a few more if you have time
jigglypuff314 (jigglypuff314):

find the height of a parallelogram if the area is 2494m and the base measures 58
jigglypuff314 (jigglypuff314):
area of parallelogram = base times height
so height = area divided by base
= 2494 / 58 =
OpenStudy (anonymous):
So it would be 43
jigglypuff314 (jigglypuff314):
yep :)

Just 2 more haha

solve for x when given x - 7 = 6
solve for y when given 2y - 6 = 8
OpenStudy (anonymous):
Alright and the last one is
jigglypuff314 (jigglypuff314):
2x - 6 + 4x = 180
5y = y + 8

so y=-3?
jigglypuff314 (jigglypuff314):
5y = y + 8 -> y = 2
OpenStudy (anonymous):
oh ok, and then x=60??
OpenStudy (anonymous):
or 31?
jigglypuff314 (jigglypuff314):
31 would be correct :)
