## infinitemoes Group Title what is the radian measure of an angle whose sine is 0.8? one year ago one year ago

if it's not in rad, multiply the arcsin by 180/pi

3. primeralph Group Title

(I like girls with smiles)

4. primeralph Group Title

Got it?

5. infinitemoes Group Title

Yes! Thank you very much. So, it says to find the radian measure of tangent -.25 now. Do I put in tan -.25 eeeerrr, am I doing this completely wrong? haha

6. infinitemoes Group Title

Sorry, I'm a lost one when it comes to trig.

7. primeralph Group Title

I got 3 questions: do you have a calculator? has anyone told you how pretty you are? what kind of calculator is it?

8. infinitemoes Group Title

no. I've been getting by on a calc on my computer this entire year. haha and thank you!

9. primeralph Group Title

okay, you're using windows?

10. infinitemoes Group Title

yes.

11. primeralph Group Title

type -.25, then click on the button that says "inv", then you'll see "tan-1" where "tan" used to be. Click that and you have an answer.

12. primeralph Group Title

got it?

13. infinitemoes Group Title

yup, thank you!

$\arcsin(0.8)=53,130102354$ $x=53,130\pi/180$ $x=0.295$
