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.
Answer:
Perimeter = 120m
Step-by-step explanation:
Let's take a peek at the denominators first off, and do a "prime factoring" on them.
25 = 5 *
527 =
3 *
3 * 3
45 =
3 *
3 *
5
the numbers in bold are repeated there more than once among the factors, and therefore we'll use them once, so our LCD will be 5 * 5 * 3 * 3 * 3, or 675.
