I JUST NEED A QUICK EXPLANATION!
The equation is "Find the remaining parts of the triangle with B=50deg, b = 5, c = 6.

Then you do the law of sine, so
sin50deg/5 = sin(c)/6

which turns into sin(c) = 6/5sin50 which equals 0.9193.

HOW DOES THIS CHANGE TO 66.82 degrees?!?!

arc sin(6/5sin50) is 66.82

anonymous · Answer

that's mean c not sin(c)

Can you explain arc sin? This is the example in the book and it just converted .9193 into66.82 degrees without any explanation!

anonymous · Answer

arc sin  is the inverse of sinc which the function is to get c

anonymous · Answer

from your calculator the symbol is sin^-1
