Answer:
There are two options: b) , c) .
Step-by-step explanation:
By Trigonometry, we know that function tangent is equal to the following identity in terms of functions sine and cosine:
(1)
If we know that and , then . Hence, we have two possibilities: b) , c) .
Answer:
y represents the pages, while x represents the minutes. for every y, there is 9/10 x, therefore the equation is y=9/10x
Answer:
100 meters in 1 minute
Step-by-step explanation:
500/5=100
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
