Step-by-step explanation:
The first one is -30 seconds
the second one is 20 meters
the third one is 0
A) 0.59 uses 2 sig figs
B) 100.6 uses 4 sig figs (the zeros in this case are significant)
C) 98.42 uses 4 sig figs
D) 1.045 uses 4 sig figs (the zero is between other sig figs so it's significant)
Every choice but choice A has 4 sig figs. So the answers are B, C, and D

3. if exterior angle = 40 degrees then the number of sides in the plygon
= 360/40 = 9 sides
So its a nonagon.
