Question

Can anyone Help me with this problem??

Answer 1

9.

Explanation:

So basically, we need to find out x. So we know that ZX = YW because ZY and XY are already congruent and it's just adding a three to the value because of YX. We can find out x.

ZX = YW

5x + 17 = 10 - 2x

x = -1

Then we can find out the value of ZX and YW by plugging in x.

5(-1) + 17 = ZX = YW = 12.

Then we see that YX is 3 so...

ZX = ZY + YX

12 = ZY + 3

ZY = 9

So the answer is 9.
