Answer:
sin(x)=1/
Step-by-step explanation:
The trigonometric identities involve trigonometric functions. Here we will be using Trigonometric identity
sin²x  = 1 /( 1+cot²x )
now cot(x)= -3
⇒ cot²x= (-3)²
⇒ cot²x= 9
sin²x= 1/( 1+9)
⇒ sin²x = 1/10
taking under root on both the sides we get
√sin²x= /
/
⇒ sin(x)=± 1/

Isn't that simply asking you to compute 30% of 20?
30              x
-----   =    ------
100           20
100x = 600
      x = 6
So, out of those 20 numbers, you would expect that 6 of them would begin with the digit 1.
