45?

OpenStudy (lollylau):

if those are angles

OpenStudy (anonymous):

I learned the exterior angle therom and it says whatever is in the inside, equal it to the outside and solve, but here, you can't do that... How would I do this?

OpenStudy (mimi_x3):

35 + 100 = 135 180 - 135 = 45 x = 180 - 45 = 135

OpenStudy (lollylau):

?!

OpenStudy (anonymous):

what? can you explain please

OpenStudy (mimi_x3):

Hm..I don't know how to explain xD You can see it by looking at the diagram.

OpenStudy (anonymous):

Ok... so what I am getting is that you add all numbers, then subtract that from 180... then I have no idea...

OpenStudy (anonymous):
