Find the values of a and b
I'm guessing the drawing should have a bit more info, like so: |dw:1358058101934:dw| ie the top is parallel with the bottom. Now, angle a + 42 = 180, and angle b + 108 = 180.
no I drew it like how it was shown... and okay
I think @agent0smith is right, we need more info
wells thats exactly what it looks like, the way i draw it i swear
@UmmmHELP the way it is drawn, I don't think it's possible to find a and b - all you can say is that: \[a + b + 42 + 108 = 360\]But this isn't enough info to find a and b. Since you aren't given any side lengths. The drawing looks like it has parallel lines, so maybe you're meant to assume they're parallel.
I dont know cause Im looking at it now and it doesnt have the lines...so u really dont know sorry haha thats just all they gave me
I mean I really dont know sorry
Well if they aren't parallel lines, there's no way to find a and b, you only know that: \[a+b = 210\]and you can't solve this for a and b. Assume they're parallel and you can find them as i showed above.
They look parallel in the drawing you gave, so you're probably safe to assume they are
Assuming they're parallel, do you know how to solve for a and b? \[ a + 42 = 180 \] \[b + 108 = 180 \]
sorry I wasnt even on the site for a while... Um I dont know..isnt it something with subtracting
Yes, in the first equation, you'd subtract 42 from both sides to find a. You can find b in a similar way.
To find b, you'd subtract 108 from both sides of the equation b + 108 = 180, but it sounds like you got it! :)
