1 AnswerMathematics8 years ago### Trigo help please ma'am/sir...!?

I got trouble understanding numbers and figures. Please help me to understand these things...

If a=579

b=673

c=? <A=?

the answers were:

c=sqrtof 673^2+579^2=888

A=sin^- 579/888=40.7

MY QUESTIONS ARE:

1. where did they get the square root & why did they use square root?

2. why is there a negative exponent of the sin? can't we use cosine instead?

3. when do we use cosine? when do we use sine and tangent?

well, it may seem easy to you but i really can't get it...

please explain...

thank you in advance...
