So, on my right triangle triangle I have here, they give all the sides and are asking for an angle
The sides are
Opp=15
Adj=8
Hyp=17
And we are looking for the x angle.

Best ResponseYou've already chosen the best response.1Do you know SOHCAHTOA? Your sine, cosine, and tangent laws?

Best ResponseYou've already chosen the best response.1Okay, since you know all three side lengths, you can use any of the three functions to determine x.

Best ResponseYou've already chosen the best response.1For example, \(\sin x = \frac{\text{opp}}{\text{hyp}}\)

Best ResponseYou've already chosen the best response.0And that is it? Just use 17 over 15 ,divide and my answer would be 1.13?

Best ResponseYou've already chosen the best response.1It's not x = 1.13. It's sin x = 1.13.

Best ResponseYou've already chosen the best response.0Ah, sorry for not using correct mathematical vocabulary.

Best ResponseYou've already chosen the best response.1No, that's not my point. The point is, you need to solve for x. Right now, you only know sin x.

Best ResponseYou've already chosen the best response.1You need to get rid of the sin.

Best ResponseYou've already chosen the best response.0Oh? How is this done?

Best ResponseYou've already chosen the best response.1One thing first. It's not 17/15, it's 15/17.

Best ResponseYou've already chosen the best response.1So, \(\sin x = \frac{15}{17} = 0.882\)

geoffb

Best ResponseYou've already chosen the best response.1To get rid of the sin, you calculate \(\sin^{1}\). On your calculator, you should have a way to do this.

Best ResponseYou've already chosen the best response.1So, \(x = \sin^{1} (\frac{15}{17})\)

Best ResponseYou've already chosen the best response.0I did not know there was such an option? Thank you.

Best ResponseYou've already chosen the best response.1You might need to hit something like 2nd function, or inverse, then hit sin.

Best ResponseYou've already chosen the best response.1You should end up with something around 60 degrees, if it's sine of 15/17.

Best ResponseYou've already chosen the best response.0This isn't my outcome, I get a decimal of 1.001

geoffb

Best ResponseYou've already chosen the best response.1Okay, so you took your amount (0.882) and hit inverse sine (sin^1) and got 1.001?

kennedav000

Best ResponseYou've already chosen the best response.0Oh but wait, that is sin(h), Sorry, personal mistake.

Best ResponseYou've already chosen the best response.1Since you knew all the sides, you could have also done \(x = \cos^{1} (\frac{8}{17})\) or \(x = \tan^{1} (\frac{15}{8})\), and gotten identical answers.

Best ResponseYou've already chosen the best response.0Odd, I get the decimal of 0.795, how does this lead to 60 degrees?

geoffb

Best ResponseYou've already chosen the best response.1What calculation gives you 0.795?

kennedav000

Best ResponseYou've already chosen the best response.0Well, seeing as I'm using the computer based calculator, this may have swayed my calculation. When typed in, it shows up as *asinh(15 /17)*

geoffb

Best ResponseYou've already chosen the best response.1Where did you type that in?

kennedav000

Best ResponseYou've already chosen the best response.0But lo, I have found my answer as you have predicted, thank you so much kind sir, It was simply a typing error.
