Answer:

Two values of x that are :

x=-\sqrt{7}-1

x=\sqrt{7}-1

Step-by-step explanation:

Given= x^2+2x-6=0

To find = Two values of x

Solution :

x^2+2x-6=0

Adding and subtracting 1 in the equation :

x^2+2x+1-1-6=0

(x^2+2\times x\times 1+1^2)-1-6=0

(x+1)^2-7=0

(x+1)^2=7

(x+1)=\pm \sqrt{7}

Two values of x that are :

x=-\sqrt{7}-1

x=\sqrt{7}-1

The measure of angle O is 7pi/6. The measure of its reference angle is.... ° and sin O is .....
scoray [572]
\frac{7 \pi }{6} is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)
\frac{7 \pi }{6} - \pi = \frac{ \pi }{6}  (or 30 degrees)

sin \frac{ \pi }{6} = \frac{1}{2}
