Question

Find the exact value of y.A- square root of 2B- square root of 6C- 3D - 3 square root of 2

Answer 1

To get the value of y, we will apply the trigonometeric ratio

From the image given,

Opposite side = y

hypotenuse = 6

so we can then use the relation:

$\sin \emptyset=\frac{opposite}{hypotenuse}$

$\emptyset=45^0$

$\sin 45=\frac{y}{6}$

$y=6\sin 45^0$$y=6\text{ x}\frac{\sqrt[]{2}}{2}=3\sqrt[]{2}$

The answer is 3 square root of 2
