Answer:
Step-by-step explanation:
First of all, we have to know that complex roots can happen only in pairs, because they are based on the square root of a negative number.
On the other hand, a third degree polynomial can only have 3 roots as solution, because the degree of the polynomial specifies how many roots would have.
So, if we only can have 3 roots, and complex roots can only happen in pairs, then f(x) would have zero complex roots or two complex roots only, those are the unique scenarios.
so the answer is 9. hope this helps.
Answer:
m∠KMJ = 72°
Step-by-step explanation:
Since, ∠KMJ and ∠JMI are complementary angles.
Therefore,
m∠KMJ + m∠JMI= 90°
m∠KMJ + 18° = 90°
m∠KMJ = 90° - 18°
m∠KMJ = 72°
Answer:
It's 72 degrees
Step-by-step explanation:
