You can arrange the 9 normal books in 9 ways, creating 10 slots where one of the three common books may be placed.

Step-by-step explanation:

There are 10⋅9⋅8 ways to choose different slots for those three books. The total number of allowable arrangements therefore is 9!⋅720=261273600

Answer:

x = 240°, x = 300°

Step-by-step explanation:

Using the identity

sin x = $\frac{1}{cosecx}$ = $\frac{1}{-\frac{2}{\sqrt{3} } }$ = - $\frac{\sqrt{3} }{2}$ , then

x = $sin^{-1}$ ( $\frac{\sqrt{3} }{2}$ ) = 60° ← related acute angle

Since sin x < 0 then x is in 3rd / 4th quadrants

x = 180° + 60° = 240°

x = 360° - 60° = 300°
