The solutions are:

Step-by-step explanation:
We have the following quadratic equation

We can rewrite the equation as follows

Now we use the quadratic formula to solve the equation
For an equation of the form
the quadratic formula is:

In this case:

Then:





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

Answer:
x=1 y=3
Step-by-step explanation:
3x+y=6 is the same as y=6-3x
2x-y=-1 is the same as y=2x+1
set them equal to each other
6-3x=2x+1
5x=5
x=1
substitute the value of x into either equation
y=2(1) +1
y=3
