The formula for working out the total interior is:
180(n-2) = 1260
So let’s rearrange by dividing both sides by 180 and find what n is:
n-2 = 7
Then let’s add 2 to both sides to find what n is:
n=9
Each interior angle is 1260/9 = 140°.
The sum of the interior angle and its corresponding exterior angle is 180°.
Therefore, the polygon has 9 sides. :)
Answer:
84
Step-by-step explanation:
4v^2 - m^2
let v=5 and m=-4
4 * (5)^2 - (-4)^2
4* (25) - (16)
100 - 16
84
B is the answer because it does not give information for the third side. We cannot assume it is equal because it is not a right triangle.
<span>(–7 + 3i) – (2 – 6i)
subtract the like terms.
-7 - 2 = -9
3i - (-6i) = 3i +6i = 9i
The answer becomes -9 + 9i</span>
