How can I finish this law of sines problem?
a/sinA = b/SinB = c/sinC 8/sin36 = 5/sinB sinB = (sin36 * 5)/8 = 0.367365783 B = 21.55 C=180 - 21.55 - 36 = 122.45 c = (sin122.45 * 8)/sin 36 = 11.48 Read More »

How would you use the Law of Sines on this problem?
The Law of Sines relates to Geometry and the angles in a triangle, not to factoring polynomials, which is what I guess you want us to do. Looking a x^4 + 3x^3 + 3x^2 + 3x + 2, we can see that -1 is a root as (-1)^4 + 3(-1)^3 + 3(-1)^2 + 3(-... Read More »

you are doing everything right 10 / sin 36 = 4 / sin b b = 13.5 or 166.401 since the side opposite of b is 4 and the one opposite a is 10 with 36 then 166 is rejected. after you do that... you add 180- (13.5 + 36) = 130.41 then u apply the ...

1) law of sines sinA/a = sinB/b = sinC/c capital letters are angles therefore sinB/b = sinC/c or simplier arcsin C = ((9sin(155))/11) = 20.23, aprox.C= 20 (20.229) therefore A=5 (4.771) when you take a ratio for side a it's better if you us...

We know that: sin(A)/a = sin(B)/b = sin(C)/c If we let C = 90°, then: sin(A)/a = sin(B)/b = 1/c Then: sin(A)/a = 1/c ==> sin(A) = a/c sin(B)/b = 1/c ==> sin(B) = b/c So if a = 3, b = 4, and c = 5, then sin(A) = 3/5 and sin(B) = 4/5; or A ≈ ...

1. A triangle ACB has a base of 12.2, angle A is 61 degrees, angle B is 14 degrees and angle C is 105 degrees. This question is poorly written because it does NOT specify which side has length "12.2". It says the "base", but is that side AC...
