how did u get b as that?
try to find sin A you won't find b there at all :P

  • Ac3
use tangent to find side b
  • Ac3
doesn't matter which angle you pick you'll get it right either way
so there's my mistake,.. tan82=5/b
  • Ac3
just remember tangent= opp/adj
yep, thats correct find b from there
b=5tan(82)
  • Ac3
so b = 5/tan(82)
|dw:1443988627702:dw| remember \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] if you want to find hypotenuse then you should use sin A =opposite/hyp
  • Ac3
your not solving for b properly you have to multiply both sides by b then divide by tan(82) bot sides
|dw:1443988722622:dw| given is opposite side of angle A and we want to find b which ration equal to opposite over adjacent
tan 82 = 5/b b*tan 82 = 5 b = 5/tan 82
oh i see
to find the length of c I believe you would set up cos90=5/c
you mean cos 8 = 5/c ??
she is using right angle
cos 90 = sin 0 = 0
if its 5/c its cos 8 or sin 82
|dw:1443988964305:dw| to find length C u don't have to use angle C use A or B
hartnn where did you get the 8 from? :)
hartnn never mind the angle :D
8 is the angle of B in degrees
but lets use sin 82 because 82 is a given information
ok :) makes sense so sin82=5/c
good, find c
5/sin82
excellent! you didn't repeat the same mistake :)
I have a good teacher :D
*blushes* :P i have an amazing student :)
