5. If WXYZ is a kite, XZ=46 and WR=21, find the measures below.

Solution
For this case weknow that XZ= 46 and WR=21
So then we can use Pythagoras theorema and we got:
[tex]21^2+23^2=WX^2[/tex]and solving we got:
[tex]WX=\sqrt[]{970}=31.1[/tex]And the measure of the angle m < ZRY is :
m < ZRY = 90º
