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.

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.

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
 one year ago

Yes, in the first equation, you'd subtract 42 from both sides to find a. You can find b in a similar way.

subtract 180?

I got..thanks

To find b, you'd subtract 108 from both sides of the equation b + 108 = 180, but it sounds like you got it! :)
