• The Journey Of X-Variable
• College Calculus Class
• Example 2 a: 5    b: ?    c: 12 A: ?    B: ?  C: 370
• Excuse me, Mr. Cumberland? How do we solve this problem?
• College Calculus Class
• ﻿First, you have to do a/sin A = c/sin C. Next, substitute 5 for (a), 12 for (c), and 37 for (sin c). Then, do sin A = 5sin37/12. Afterward, divide 5sin37 & 12 to get sin A = 0.2508. Finally, your answer for sin A = 14.50 ﻿
• Example 2 a: 5    b: ?    c: 12 A: ?    B: ?  C: 370
• 4. a: 19     b: 17﻿    c: ? A: ?    B: ?  C: 800
• In a mathematical world, there were two college students trying to discover how to solve law of sines.
• College Calculus Class
• 4. a: 19     b: 17﻿    c: ? A: ?    B: ?  C: 800

• A boy named Michael and girl named Jessica are sitting in a classroom and they going to ask their professor Mr. Fitchburg how to solve a law of sine problem.  ﻿
• College Calculus Class
• 4. a: 19     b: 17﻿    c: ? A: ?    B: ?  C: 800
• Example 2 a: 5    b: ?    c: 12 A: ?    B: ?  C: 370
• First, Mr. Fitchburg is going to tell his students how to find angle A.
• The End Of Calculus Class
• ﻿﻿Mr. Fitchburg, we thank you so much for teaching us how to solve law of sines. It means a lot to us and we could've have done it without you.
• ﻿You guys are welcome. Come back anytime if you have a problem with any math problems.
• Then afterward, Mr. Fitchburg is going to tell his students how to find angle B.
• ﻿First, you do B = 180 - (C + A). Next, substitute 37 for (C) and 14.5 for (A). Then, plug in the numbers and you get B = 180 - (37 +14.5). Finally, your answer for angle B is 128.50﻿
• Lastly, Mr. Fitchburg is going to tell his students how to find side b.
• ﻿﻿Finally, the last thing to do is b/sin B = c/sin C. Next, you substitute 128.5 for (sin B), 12 for c, and 37 for (sin c). Then, after substituting, you do b = 12sin128.5/sin37. Finally, you solve for b, and your answer is b = 15.6.
• ﻿After class, Michael and Jessica thanks Mr. Fitchburg for all their help on how to solve a law of sine problem.
