What are the coefficients in the polynomial 5x^2 + 2x - 4?
a: 5, 2
b: -5, -2
c: 5, 2, -4
d: 5, -2, -4

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

too hard the other guy did it
