Best ResponseYou've already chosen the best response.0so let me explain im trying to find a okay c=96.3, b=145.67 , B=39.5degrees, C=74.2degrees,

Best ResponseYou've already chosen the best response.0law of sines is a/sinA=b/sinB

Best ResponseYou've already chosen the best response.1Sine rule says: SinA/a = SinB/b = SinC/c

Best ResponseYou've already chosen the best response.0okay i understand that waitt why is it sina/a instead of a/sin a

Best ResponseYou've already chosen the best response.1SinA/a = Sin(39.5)/145.67 SinA = a*something

Best ResponseYou've already chosen the best response.1Because they mean the same thing. A/B = C/D => B/A = D/C

Best ResponseYou've already chosen the best response.1You can find angle A by simply subtracting angles B and C from 180.

Best ResponseYou've already chosen the best response.0okay i understand which would be 66.8

Best ResponseYou've already chosen the best response.1Then, use this: SinA/a = Sin(39.5)/145.67 SinA = a*something SinA/something = a To find a.

Best ResponseYou've already chosen the best response.1SinA/a = SinB/b = SinC/c IS SAME AS a/SinA = b/SinB = c/SinC

Best ResponseYou've already chosen the best response.0but then a would be .00436

GT

Best ResponseYou've already chosen the best response.1That "something" in my expression is 0.00436. Divide Sin66.8 by that "something" value. Then, you get the value of a.

Best ResponseYou've already chosen the best response.0really then let me try again...... im still not getting that are you multiplying or dividing

Best ResponseYou've already chosen the best response.1SinA/a = Sin(39.5)/145.67 SinA = a*0.00436 a = SinA/0.00436 a = Sin66.8/0.00436 a = 210.5

Best ResponseYou've already chosen the best response.0okay, so instead of 66.8 its 66.3

Best ResponseYou've already chosen the best response.1Punch it into the calculator and you get slightly different number from 210.5

Best ResponseYou've already chosen the best response.1SinA/a = Sin(39.5)/145.67 SinA = a*0.00436 a = SinA/0.00436 a = Sin66.3/0.00436 a = 210

Best ResponseYou've already chosen the best response.1Check your calculator first. I'm guessing you're getting different answers because your calculator is not in degree mode. That's why it's treating your angles differently.

Best ResponseYou've already chosen the best response.1How in the world can a length of a side of a triangle be negative? Can you show the arithmetic you used to get that number?

Best ResponseYou've already chosen the best response.0yeppp m ycalculator wasnt in degree mode so let me try again

Best ResponseYou've already chosen the best response.1Good....close enough to 210. :)

Best ResponseYou've already chosen the best response.0next problem b=58.2 c=68.3 C=51.3 degrees were gunna find a

Best ResponseYou've already chosen the best response.1At this point, it is simply plugging in values into that sine rule ratios and cranking out numbers in a calculator. There is not much help you need.

Best ResponseYou've already chosen the best response.0yeaa but i want to do it my self then have someone do it so i can nn check my answer to make sure its correct

dessyk

Best ResponseYou've already chosen the best response.0is my answer correct thats all im asking

Best ResponseYou've already chosen the best response.1Angles are almost close to each other. So, side lengths have to be close to each other too.

Best ResponseYou've already chosen the best response.0well i must be doing something wrong but sin68.3/51.3=.018111746

Best ResponseYou've already chosen the best response.1b=58.2 c=68.3 C=51.3 degrees SinB/b = SinC/c => SinB = 58.2 * Sin(51.3)/68.3 => SinB = 0.665 B = 41.68

Best ResponseYou've already chosen the best response.0becuase i couldnt find A or B so i figured they were the same by suntracting 18051.3

dessyk

Best ResponseYou've already chosen the best response.0ohhh ok so u must follow the formula

GT

Best ResponseYou've already chosen the best response.1Now that you know B, you find A by doing 180  51.3  41.68 = 87

GT

Best ResponseYou've already chosen the best response.1SinA/a = SinC/c => a = c * SinA/SinC => a = 68.3 * Sin(87)/Sin(51.3) => a = 87.4

Best ResponseYou've already chosen the best response.0@dessyk The following variations of Law of Sines are the same: \[\frac{a}{\sin(A)} = \frac{b}{\sin(B)}=\frac{c}{\sin(C)}\] and \[\frac{\sin(A)}{a}=\frac{\sin(B)}{b}=\frac{\sin(C)}{c}\]

Best ResponseYou've already chosen the best response.0i have another question but hoew did you get 41. sometrhing but i got 45.42

GT

Best ResponseYou've already chosen the best response.1You mean for B = 41? I did the inverse sine function on the value 0.665.

dessyk

Best ResponseYou've already chosen the best response.0yes, ohh reallyy you see im confused now i thought u just i thought u just took .6650*68.3=45.42

GT

Best ResponseYou've already chosen the best response.1Sin(B) = 0.665 => B = inverse sine (0.665). On the calculator, you have to first press 0.665. Then, inv button, then the sin button.

Best ResponseYou've already chosen the best response.0i didn't see above but u can find it very easily.. the formula is sin a / a = sin b / b = sin c / c or a /sin a = b / sin b = c / sin c use any of them what caters ur problem
