Question

Choose the correct ratio.

$\sin 40 = \frac{w}{28}$
$\cos 40 = \frac{w}{28}$
$\tan 40 = \frac{w}{28}$
$\sin 40 = \frac{28}{w}$

hint Hint:

Sin x = opposite side / Hypotenuse side

The correct answer is: $sin invisible function application 40 equals w over 28$

Since we have to find the hypotenuse side and opposite side and angle is given so we use sin ratio
Sin x = opposite side / Hypotenuse side
$sin invisible function application 40 equals w over 28$
