Which of the following is the complete list of roots for the polynomial function f (x) = (x squared + 2 x minus 15) (x squared + 8 x + 17)? –5, 3 –5, 3, –4 + i, –4 – i –5, 3, –4 + i, 4 + i –4 + i, –4 – i

answer: idk

step-by-step explanation:

your answer is -9

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
