-2, -1, 0
These would be the options
ok so basically x=1/2 which is the exact form. and the decimal form is x=0.5 Step-by-step explanation:
Answer:
π\6
Step-by-step explanation:
The reference angle is the smallest angle measured from the terminal side of the angle (where the angle ends) to the x axis. The reference angle is an acute angle (i.e less than 90° or π/2)
For O = 11π/6 = 1.833π
1.833π is in the fourth quadrant between 3π/2 radians and 2π radians. Since it is in the fourth quadrant, the reference angle is given as:
reference angle = 2π - 11π/6 = π\6
It’s C
Because if you divide 12/9 it equals 1.333 and that’s the option C
20 + x = 10
20 + -10 = 10
x = -10
hope this helps you
