Do you know SOHCAHTOA?
Your sine, cosine, and tangent laws?

Yes

Okay, since you know all three side lengths, you can use any of the three functions to determine x.

For example, \(\sin x = \frac{\text{opp}}{\text{hyp}}\)

And that is it? Just use 17 over 15 ,divide and my answer would be 1.13?

It's not x = 1.13. It's sin x = 1.13.

Ah, sorry for not using correct mathematical vocabulary.

No, that's not my point. The point is, you need to solve for x. Right now, you only know sin x.

You need to get rid of the sin.

Oh? How is this done?

One thing first. It's not 17/15, it's 15/17.

Got it

So, \(\sin x = \frac{15}{17} = 0.882\)

So, \(x = \sin^{-1} (\frac{15}{17})\)

I did not know there was such an option? Thank you.

You might need to hit something like 2nd function, or inverse, then hit sin.

You should end up with something around 60 degrees, if it's sine of 15/17.

This isn't my outcome, I get a decimal of 1.001

Okay, so you took your amount (0.882) and hit inverse sine (sin^-1) and got 1.001?

Oh but wait, that is sin(h), Sorry, personal mistake.

No worries.

Odd, I get the decimal of 0.795, how does this lead to 60 degrees?

What calculation gives you 0.795?

Where did you type that in?

Good stuff! You're very welcome. :)

I shall be on my way! Good day to you, and thank you for your time.

You too, David! Cheers!
