The answer is 25.9. To find it add the other sides (21.5 + 32.4 + 28.7 = 82.6) Then take the perimeter (108.5) and subtract (108.5 - 82.6 = 25.9)

Answer is 2 SIMPLE
Step-by-step explanation:
Step-by-step explanation:
Complex roots or imaginary roots must come in conjugate pairs. If -4i is a root, that means 4i is also a root.
A possible polynomial is:
y = (x + 4i) (x − 4i)
y = x² − 16i²
y = x² + 16
Answer:
900
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is given by the formula:

The polygon given has 7 sides. Substitute 7 for n. Thus:

The sum of the interior angles is 900 degrees.
