It is 0.23 because 84-61 is 23 and 23 Divided by 100 is 0.23
Answer: x= 29°
Step-by-step explanation: Add angles D and C. Subtract from 180.
58/2 = 29
F(x) = x^3 + 2x^2 - x - 2
<span>f(x) = x^2(x + 2) - (x + 2) </span>
<span>f(x) = (x^2 - 1)(x + 2) </span>
<span>f(x) = (x + 1)(x - 1)(x + 2) </span>
<span>Roots: -1, 1, -2 </span>
