Ok, What do you do when two equations that should yield the same answer dont? For example when finding the area of a SSA triangle:(adsbygoogle = window.adsbygoogle || []).push({});

A= 25 degrees

side a = 100

side b = 200

Now, I know this triangle gives two possible answers but I am just concentrating on answer 1, when using the law of sines you get

B= 57.6973 degrees

which leaves C= 97.3027 degrees

Now, if you use the equation:

(a^2*sinB*sinC) / (2sinA) You get 9,958.48 inches^2

But, if you use .5(a)(b*sinC) which should work also, you get 9,925.88 inches^2

If these equations are equivalent then why do they give different answers? Is it just calculator rounding?
