The value of cos A is √(1 + x²)/ (1 - x²) /√1 + x
<h3>Trigonometric ratios</h3>
It is important to note that
sin A = opposite/ hypotenuse
cos A = adjacent/ hypotenuse
Then,
opposite =
Hypotenuse =
Let's find the adjacent side using the Pythagorean theroem
cos A = x/hypotenuse
cos A = √(1 + x²)/ (1 - x²) /√1 + x
Thus, the value of cos A is √(1 + x²)/ (1 - x²) /√1 + x

Answer:
65%
Step-by-step explanation:
We will find the percentage of people by dividing the amount of people who were satisfied by the total amount of people surveyed.
1820 / 2800 = 0.65
Then we convert this number into percentage by multiplying it by 100
0.65 * 100 = 65
