Answer:

{x}^{2}  - 6x + 11 = 0 \\ x =  \frac{ - b± \sqrt{ {b}^{2}  - 4ac} }{2a}  \\ x =  \frac{6± \sqrt{ - 8} }{2}  \\ x =  \frac{6±2i \sqrt{2} }{2}  \\ x = 3±i \sqrt{2}

Answer:

x=3\pm\sqrt{2}i

Step-by-step explanation:

x^2-6x+11=0

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{-(-6)\pm\sqrt{(-6)^2-4(1)(11)} }{2(1)}

x=\frac{6\pm\sqrt{36-44} }{2}

x=\frac{6\pm\sqrt{-8} }{2}

x=\frac{6\pm2\sqrt{2}i }{2}

x=3\pm\sqrt{2}i

I'm stuck: 20 POINTS AND BRAINLIEST!
Sedbober [7]

Answer:

see explanation

Step-by-step explanation:

The secant- secant angle PRS is half the measure of the difference of the intercepted arcs, that is

\frac{1}{2} (PD - QS) = 50 ( multiply both sides by 2 )

PD - QS = 100, that is

12x + 8 - (4x + 4) = 100

12x + 8 - 4x - 4 = 100

8x + 4 = 100 ( subtract 4 from both sides )

8x = 96 ( divide both sides by 8 )

x = 12

Thus

arc PD = 12(12) + 8 = 144 + 8 = 152°

arc QS = 4(12) + 4 = 48 + 4 = 52°
