Solve each equation by the quadratic formula.
-x^2+5x-6=2

x=  −5±√−7  / −2 --> (No Real Solution)

Step-by-step explanation:

−x^2+5x−6−2=2−2

−x^2+5x−8=0

x=  −(5)±√(5)2−4(−1)(−8)  / 2(−1)

x=  −5±√−7  / −2

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
