SinA=√1-x÷√1+X<br> Find the value of cosA

Irina-Kira [14]

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 = $\sqrt{1} - x$

Hypotenuse = $\sqrt{1} + x$

Let's find the adjacent side using the Pythagorean theroem

$(\sqrt{1} + x)^2 = (\sqrt{1 -x } )^2 + x^2$

$1 + x^2 = 1 - x^2 + x^2$

$x = \sqrt{\frac{1 + x^2}{1 -x^2} }$

cos A = x/hypotenuse

$cos A = \frac{\sqrt{\frac{1+x^2}{1 -x^2} } }{\sqrt{1} +x}$

cos A = √(1 + x²)/ (1 - x²) /√1 + x

Thus, the value of cos A is √(1 + x²)/ (1 - x²) /√1 + x

Sean spends 35 minutes revising for his exam. Erica spends 1 hours 15 minutes revising for her exam. Work out the total time, in

Alja [10]

The total time spent in minutes is 110 minutes

<h3>How to determine the total time?</h3>

The given parameters are:

Erica = 1 hour, 15 minutes
Sean = 35 minutes

The total time is calculated as:

Total = Erica + Sean

So, we have:

Total = 1 hour, 15 minutes + 35 minutes

1 hour = 60 minutes

So, we have:

Total = 60 minutes + 15 minutes + 35 minutes

Evaluate the sum

Total = 110 minutes

Hence, the total time spent is 110 minutes
