# Math Help - Applying the Laws of Sines or Cosines

1. ## Applying the Laws of Sines or Cosines

Solve the triangle.

B = 36°, a = 41, c = 17

choices are

b ≈ 29, C ≈ 20, A ≈ 124
b ≈ 44, C ≈ 20, A ≈ 124
b ≈ 29, C ≈ 121, A ≈ 23
b ≈ 44, C ≈ 24, A ≈ 120

2. ## Re: Applying the Laws of Sines or Cosines

These look like test questions..

So all I will put is this:

$b^2 = a^2 + c^2 - 2acCos(B)$

Where angle B is opposite side b
