can you convert radians to degrees by replacing pi with 180
yes
Polygon FGHIJ is the result of the rotation of ABCDE.
A = F ⇒ 117°
B = G ⇒ 90°
C = H ⇒ 127°
D = I ⇒ 90°
E = J ⇒ 117°
The measure of angle BCD remains the same because the rotation involves the whole polygon. Thus, it is still 127°
The population of the bacteria 96 minutes from now is 12.
I think it is .1324 but I need a little more details.
