You know that all four sided polygons have a total angle measure of 360.

add all the sides you have:

65 + 90 + 15 = 170

Subtract 170 from total(360)

360 - 170 = 190

Missing angle: 190

[tex]360=65+90+15+x[/tex]
[tex]360=170+x[/tex]
     -170    -170
[tex]190=x[/tex]
[tex]mCA=190 degrees[/tex]

I cant give side lengths until I know a couple, and then that would require some triginometry, which I don't feel like doing right now, to be frank.
