Find the measure of the acute angle x, if :
sin(x)=0.0175; sin(x)=0.5015; cos(x)=0.06814; cos(x)=0.0670.

I know that Sin(x)=opp./hyp. and that cos(x)=adj./hyp. but i have no clue about how to find the xs in these equations

  1. your calculator has a 2nd function button of some kind, which makes
    sin into sin^-1
    so, if sin(x) = 0.0175, x = sin^-1(0.0175) = 1.00°
    so, reread this section of your text, and the user guide for your calculator.

  3. I just did all the problems in the packets and when i turned them in the were wrong, i did sin^-1=0.5015; cos^-1=0.06814; cos^-1=0.067 to find x is that what i'm supposed to do?

  4. I also got them wrong until I put the degree sign on my homework, so don't forget the degree sign.
