Triangle P N M is shown. The length of P N is 7, the length of N M is 8, and the length of M P is 11.
Law of cosines: a2 = b2 + c2 β 2bccos(A)
Which equation correctly applies the law of cosines to solve for an unknown angle measure?
72 = 82 + 112 β 2(8)(11)cos(N)
82 = 72 + 112 β 2(7)(11)cos(M)
72 = 82 + 112 β 2(8)(11)cos(P)
82 = 72 + 112 β 2(7)(11)cos(P)
