To find:
The measure of angle C.
Solution:
Law of Cosines:


Substituting the given values, we get




Taking cos inverse on both sides, we get


Therefore, the measure of angle C is 90 degrees.
Answer:
y = (x - 4)² - 26
Step-by-step explanation:
To complete the square, all we need to do is take term -8x, and add enough to make the equation come out to the square of half that. Half of -8 is -4, so we need to add 26 to the equation to end up at 16:

Giving us the final result
It’s c because there’s only one apple
= - 4.2x + 3 + 2.5x - 6
= 2.5x - 4.2x + 3 - 6
= - 1.7x - 3
