(x + 5) is a factor of x2 + 2x – 15. What is the other factor?

(x-3)

Step-by-step explanation: First look what which two numbers would multiply to -15 and add to 2. In this case, it's 5 and -3 because 5x-3=15 and 5+(-3)=2.

So the other factor is (x-3)

To check your work, simply multiply

(x+5)(x-3) = x2 + 2x - 15

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.
