Answer 5

What makes you think it does?

Answer 6

its the answer in the book

Answer 7

Perhaps the left hand side of that equation is not correct :-)

Answer 8

nope. im studying for an exam and it gives you the solution to some problems to show you how to do it. and im going through the steps and that what it says

Answer 9

Show me the entire problem, please.

Answer 10

here is a photo if you dont beleive me ill write out the entire problem one sec

Answer 11

That's a completely different statement than you gave us, even accounting for the picture being reversed :-)

\[\sin A = \frac{5 \sin 111.8^\circ}{10}\rightarrow \text{angle }A = 27.7^\circ\]

\[\sin A = \frac{5*0.928486}{10} \approx 0.464243\]\[A = \sin^{-1} 0.464243 \approx 0.48278 \text{ radians} = 27.6612^\circ\]

Answer 12

ooooh okay so inverse sine.
