x-intercept means f(x) = 0
(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9
There are two points which are x-intercepts. They are (8,0) and (-9,0).
Your missing angle will be 73 degrees, because the angles all add up to 180. So you add 33 and 74 then subtract that from 180
Note that if a + bi is a root of P(x) = 0, then a – bi is also a root of P(x) = 0.
In this case, i and 7 + 8i are two roots of P(x) = 0. So –i and 7 – 8i are two additional roots of P(x) = 0.
The opposite angles of a parallelogram are equal. Therefore, for parallelogram KLMN, <K = <M
