http://prntscr.com/9w57kh I'm guessing the answer is 70?

@AihberKhan

OpenStudy (welshfella):

XY is a line segment not an angle

OpenStudy (anonymous):

right so you could use 70 to find it

OpenStudy (welshfella):

what side on ABCD corresponds to XY?

OpenStudy (welshfella):

Yes the figures are congruent

OpenStudy (ghostedly):

So, 70 is, or not the answer?

OpenStudy (welshfella):

no 70 is the number of degrees in the angle C

OpenStudy (welshfella):

Look at the lengths of the sides

OpenStudy (ghostedly):

So what would XY be?

OpenStudy (ghostedly):

I kind of get confused working with these.

OpenStudy (welshfella):

which side in ABCD is equal to XY?

OpenStudy (ghostedly):

BC

OpenStudy (welshfella):

If you flip ABCD you'll see it fits exactly on top of WXYZ

OpenStudy (welshfella):

Yes BC - and what is the length of BC?

OpenStudy (welshfella):

Its written in black.

OpenStudy (ghostedly):

10

OpenStudy (welshfella):

right so XY = BC = 10

OpenStudy (ghostedly):

My answer is 10? I think I'm starting to understand now.

OpenStudy (welshfella):

yes each side in WXYZ = corresponding side in ABCD because they are conguent

OpenStudy (welshfella):

conguent means they are the same in evry way - angles and sides are same.

OpenStudy (welshfella):

so for example <Y = <C = 70 dgrees

OpenStudy (welshfella):

and CD = YZ = 8

OpenStudy (welshfella):

< W is equal to <A which is 120 degrees

OpenStudy (ghostedly):

You were a great help, thanks!
