Also, what do they mean by write the properties?http://www.flickr.Thank you!-1A quadrilateral must equal to 360.......
I need help with 1acd,2 and 5 I missed part of todays lesson, so I didn't get the whole lesson taught. I already know the answer (back of sheet), but I'd prefer it if someone were to explain it to me step-by-step. Also, what do they mean by write the properties?

1A quadrilateral must equal to 360.
a: w+79+113+104=360 Solve.
c: 95+150+70+y=360 Solve.
d: 160+65+20+z=360 Solve.

2.Theorem 11.1: Sum of measures of interior angles of a convex is (n-2)180.
Quadrilateral is a convex.
Since you know how many angles, solve n= # of angles which is 4 so (4-2)180= 360. Then add all angles
40+90+120+ x(4th angle)= 360. Then solve.
5. Two consecutive angle must equal to 180. Do the same with b and c. According to Theorem 6.4.
a: w= 110, x= 70
b: y=138, z=42
c: c=125, a=55, d=125
