I am thinking we can solve this with Cosine Law and maybe Sine Law
OpenStudy (btaylor):
You want to use the law of sines. \[\frac{\sin(A)}{A} = \frac{\sin(B)}{B}\]

Yep there it is BTaylor posted Sine Law
OpenStudy (btaylor):
A = 24, angle A = 67.38
B = 26, angle B = X
OpenStudy (anonymous):
so X is 26
OpenStudy (anonymous):
\[ \frac{\sin 67.38}{24} = \frac{\sin B}{26}\]
\[ \frac{26\times\sin 67.38}{24} \]
OpenStudy (btaylor):
no, you want to rearrange the equation to find X.
\[\sin(X) = 26 \cdot \frac{\sin(67.38)}{24}\]

What did you get?
OpenStudy (anonymous):
That is a 90 degree angle Correct?
OpenStudy (btaylor):
yes, it is.
OpenStudy (anonymous):
I just noticed it LOL
OpenStudy (anonymous):
So you do not need to use Cosine or Sine Law lol

lol so is it .999 thats what i got.. so 1
OpenStudy (anonymous):
At 90 degrees sine is (0,1) and cosine is (1,0)
OpenStudy (anonymous):
??? it is (0,1)
im so confused
OpenStudy (anonymous):
the sine of 90 sine(90) = 1
OpenStudy (anonymous):
the angle is 90 degrees. That is x
