WebThe calculator will solve the given triangle using the law of cosines (wherever possible), with steps shown. Explain mathematic problem Math is the study of numbers, shapes, and patterns. WebFind the remaining sides and angle C. Answer:To find C, we simply use the formula ∠A+∠B+∠C=180°. Therefore, ∠C=180°-45°-60°.We obtain C=75⁰. By the Law of Sines, $${a\over sin45°} = {b\over 60°} = {22 \over sin 75°}$$ Therefore, $$ a = {22 \; sin 45° \over sin 75°} = 16.11 cm $$ $$ b = {22 \; sin 60° \over sin 75°} = 19.72 cm $$
