1 radian = 180/pi
5 radians = x
X= 5• 180/pi
= 900/pi
= 286.6
(x^2 - 4^2)^2 = x^4 - 4^4
(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6
The Angela's solution is wrong cause when you multiply you get a different answer.
I'm not 100% sure but my best guess would be a rectangle. ( do not give brainliest if wrong, i wanna make sure its right)
