Answer:
Step-by-step explanation:
a
sum of angles of a quadrilateral=360°
4x+5x+20+5x-10+3x+10=360
17x=360-20
17x=340
x=340/17
x=20
b.
sum of angles= (n-2)×180
where n is the number of sides.
5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180
20x+1=720
20x=719
x=35.95

Answer:
The net change is - $0.30
Step-by-step explanation:
3.5 - 3.7 = -.2
-.2 + 3.3 = 3.1
3.1 - 3.4 = -.3
