Can you help me? I think it is 35. Im failing this class and need help

jim_thompson5910 · Answer

35 is correct

you subtract the arc measures (big - small) and then divide by 2

jim_thompson5910 · Answer

coincidentally, they use the same numbers in that page I gave you

So how would i get an answer from that? I posted another pic with the x's because they did not show up the first time

jim_thompson5910 · Answer

So we have this quadrilateral

|dw:1401657569934:dw|

jim_thompson5910 · Answer

then use the idea that all 4 angles of a quadrilateral must add to 360 degrees

anonymous · Answer

and im officially lost

jim_thompson5910 · Answer

what are these angles here

|dw:1401657827627:dw|

anonymous · Answer

45?

jim_thompson5910 · Answer

those are square angle markers to denote right angles

right angles are always 90 degrees

anonymous · Answer

ahh okayy. so 90 and 90 is 180? right?

jim_thompson5910 · Answer

so you will have these 4 angles: x, 90, x, 90
