Answer: The value of cos theta is -0.352.
Step-by-step explanation:
Since we have given that
We need to find the cos theta between u and w.
As we know the formula for angle between two vectors.
So, it becomes,
Hence, the value of cos theta is -0.352.
The shape has 7 sides.
The sum of the interior angles is (7-2)180 = 5 * 180 = 900 degrees.
Divide the total sum by 7:
X = 900 /7 = 128.6 degrees.
Your answer would be 64. There are two sides on a coin. 2^6 would be 64.
Hope this helps.
