i am pretty sure using law of sines it is 54.9535....
OpenStudy (anonymous):
so if you round 55
OpenStudy (anonymous):
54/sinA = 76/sin64 degrees
OpenStudy (anonymous):
what do i do after that?

i did sinx/54 = sin76/64
then multiply both sides by 54 to get
sinx = (54sin(76))/65
then inverse sine or sin^-1 of [ (54sin(76))/64 ]

would it be 40 degrees

I crossed multiplied which gave me 54/sinA=85..... sinA=.6353 ...... 39degrees
OpenStudy (anonymous):
I'm not sure if I'm right.
OpenStudy (tkhunny):
What's the dilemma? You have the right ratio, \(\dfrac{54}{\sin(x)} = \dfrac{76}{\sin(64º)}\). Use your calculator and you'll be done in a moment.
"Cross Multiply" doesn't mean anything. Never do that.
SOLVING for \(\sin(x)\) gives \(\dfrac{54\cdot \sin(64º)}{76} = 0.63861682237\)

That's pretty much exactly what I did and i got 39 degrees which technically is 40
