Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
Answer: use x+4 to divide x³+2x²-23x-60
x² -2x-15
__________
x+4 √x³+2x²-23x-60
-(x³+4x²)
-2x²-23x-60
-(-2x²-8x)
-15x-60
-(-15x-60)
Factorize x²-2x-15
x²-5x+3x-15
x(x-5)+3(x-5)
(x-5)(x+3)
