[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab \cos(c) \\ {x}^{2} = {130}^{2} + {25}^{2} - 2(130)(25) \cos(105) \\ {x}^{2} = 16900 + 625 - 6500 \cos(105) \\ {x}^{2} = 17525 + 1682.3 \\ {x}^{2} = 19207.3 \\ x = \sqrt{19207.3} \\ x = 138.59[/tex]

Answer : 138.6 yards after rounding off

Hope this helps. - M
