Answer:
8
Step-by-step explanation:
Use the pythagorean theorem. The hypotenuse (c) is 10, and one of the sides, let's say (b), is 6. Therefore, we need to solve for a and plug and chug. Let's do that:
Now let's plug in what we know:
Therefore, a = x = 8
By using the definition of the inverse cosine function, we will see that:
<h3>How to complete the expression?</h3>
We have the expression:
Remember that if:
Then, in what do we need to evaluate the cosine function to get an output equal to zero?
Then:
Then we can replace the question sign with a 2.
