#### Explanation:

Since this is a right triangle, we are able to use the

We know the lengths of the opposite side from ∠H and the hypotenuse, so we will use the sin function.

Using your calculator, find the value of

Without clearing the calculator (a.k.a. leaving what is on the screen there) hit

Here are a couple things to remember when you see questions like this:

- Determine which side lengths you know so that you can decide which function to use (
#tan,sin,cos# ) - When you have the form like the one that we had in this question (
#sin∠H=0.42857...# ) remember to hit#2nd# and**then the function**. Or, depending on your calculator, you should use#sin^-1,cos^-1,tan^-1# instead.
