Using the Law of Sine or Cosine, solve for the unknown variable (round to the
nearest tenth)

HELP QUICK PLEASE

Law of Sines always came easier to me since it was just simple cross multiplication.

The formula consists of a/sinA=b/sinB=c/sinC.

However, this one cannot be used for Law of Sines because one more angle isn't given. So off we go to Law of Cosines.

This one is simpler. The formula is  c^2 = a^2 + b^2 − 2ab cos(C)

This one is easier to do. Let's designate all sides a variable. Let's just say 47 is a, 56 is b, and c is x.

Let's fill in the numbers

c^2=47^2+56^2-2(47)(56)cos124

c^2=2209+3136-(5264cos124)

c^2=5245-(-2895.2)

c^2=5245+2895.2

c=90.22

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

there were a lot of them but the first one to pop up on a google search was bts
