Answer C
Step-by-step explanation: lol idk
We notice a factor of 2x in both
2x(5x^2+4x-3)
trial and error
(5x-3)(x+1) yeilds 5x^2+2x-3, nope
(5x+3)(x-1) yeilds 5x^2-2x-3, nope
(5x-1)(x+3) yeilds 5x^2+14x-3, nope
(5x+1)(x-3) yeilds 5x^2-14x-3, nope
simplest form is
2x(5x^2+4x-3)
16-gon = 2,520 deg
2,520 divided by 16 = 157.5
157.5 deg
Answer:
Reference angles are always acute.
We can find the reference angle with the "formula"
π
−
θ
, where
θ
is our given angle.
We can plug
5
π
6
into our expression to get
π
−

Thus, our reference angle is
π
6
