For this problem, SSA, we use the Law of Sines We are given: - angle A (87<span>°</span>) - side length a (22) - side length c (12) we will plug these into the formulas to solve for the missing values I'll try to get these as exact as possible ( you can approximate if needed)
<span><span>First: Use the Law of Sines to find angle G.</span><span> sin G / c =sin A / a</span><span> sin G / 12 =sin(87°) / 22</span><span> sin G = (0.999 x 12) / 22</span><span> sin G =<span>0.545 </span></span><span> G =<span>sin-1(0.545)</span></span><span> G =33.005° </span>Then: Find remaining angle by subtracting the other angles from 180°.<span> B =180° - G° - A°</span><span> B =180° - 33.005° - 87°</span><span> B =59.995° Lastly</span><span>: Use the Law of Sines to find side c. </span><span> b / sin(B) =a / sin(A)</span><span> c / sin(59.995°) =22 / sin(87°)</span><span> c =(sin(59.995°) x 22) / sin(87°)</span><span> c =19.078
Hope this helps :) (sry it took a while)</span></span>
