# Question #88157

#### Explanation:

The picture isn't that clear, however I'm considering that the side marked 0 is the one you need to find.

So in the right angle triangle the side marked 0 is the hypotenuse. And the given side is opposite to the known angle - 45.

So since we know the opposite side and we have to find the hypotenuse, we use the sin function.

$\sin 45 = \frac{60}{x}$ where x is the hypotenuse.

So solving for x -----> $x = \frac{60}{\sin} 45$
$x = 60 \sqrt{2} = 84.85 \ldots$
