Which equation correctly uses the law of cosines to solve for the length s?
92 = 52 + 102 - 2(s)(10) cos(100°)
9 = s + 10 - 2(s)(10)cos(100)
102 = 52 + 100 – 2(s)(10)cos(100)
S2 = 92 + 102 - 2(9)(10)cos(100)

Which equation correctly uses the law of cosines to

solve for the length s?
92 = 52 + 102 - 2(s)(
