given a triangle with a = 19 degrees A=43 degrees and B=14 what is c?
a = 19 degrees A=43 degrees B=14 c=? is the little a or the big A the angle?
A, big sorry
so like this then: a=19 A=43 degrees B=14 c=?
so is a=19 A= 43 degrees B = 14 degrees c = ?
so first thing we want to do is find what Angle C is using the concept that the sum of the interior angles = 180 degrees |dw:1384401733429:dw|
so angle c would equal 123
degrees
yep. now use the 'law of sin' to figure out what the length of little c is |dw:1384401950607:dw|
cool beans, so what do i do next? :O
law of sin its this: \[\frac{ c }{ Sin(C) } = \frac{ b }{ Sin(B) }=\frac{ a }{ Sin(A) }\]
pick either the b's or the a's, plug in the numbers then solve for c
okay, but can you show me so i can have the full idea, please? :)
\[\frac{ c }{ \sin(123) }=\frac{ 19 }{ \sin(43) }\]
the answer would be 27.45 am i right? :D
no im wrong nvm, keep going por favor? :D
mmm... do your math again. you can get it ^_^
omg i suck at this. okay so this is what i did 19 ------ = 27.85 sin (43)
which makes no sense.
