Answer:
Step-by-step explanation:
We require to create 2 equations with the repeating number placed after the decimal point.
let x = 0.055555 ( multiply both sides by 10 and 100 )
10x = 0.555555 → (1)
100x = 5.55555 → (2)
Subtract (1) from (2) to eliminate the repeating decimal
90x = 5 ( divide both sides by 90 )
x = =
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
