hi,

i need to try and find the missing angle from this shape;

Attachment 20577

would this be correct, sin?= 6xsin96/10= 0.6, inverse sin(0.6)= 36.87

answer= 36.87????

thanks

It's better to avoid using x to mean multiply. 6sin(96) is easy to understand. Let be the angle you need to find

**Never**round off halfway through a question, especially to one decimal place!

You've got the method, you just need to look at your rounding - Jan 24th 2011, 09:35 AMAckbeet
Your approach is certainly correct (law of sines). I get a very slightly different answer:

I got the impression the answer was prematurely rounded to 0.6 since
