would those angles be equal to each other? here's the image again angle 1 = 4 = 5 = 8 angle 2 = 3 = 6 = 7 angle 1 + 2 = 180 angle 3 + 4 = 180 angle 5 + 6 = 180 angle 7 + 8 = 180 angle 3 + 5 = 180 angle 4 + 6 = 180

AZ:

so would the two angles you drew be equal to each other or would they add up to 180?

boredfr:

Ummmmmmmmmmmmmmmmmmmmmmmmmm they are the same set up as the last one ._. so um equal?

AZ:

what do you mean by the last one? if they're equal then it would angle = angle but are they equal or should the angles add up to 180?

AZ:

|dw:1616893086398:dw| a + b = 180 c + d = 180 a + c = 180 b + d = 180

boredfr:

Ack =180 ig?

AZ:

yes they add up to 180 so 3x+5 + 7x-15 = 180 x = ?

boredfr:

x=18?

AZ:

mhmm not quite, recheck your work
