I'm trying to solve what seems to be a basic triangle question but I keep getting strange results.
So I did
Then I did
So now I can say angle
Making the final triangle look like this
I don't think it is correct though, I'm trying to use SohCahToa to solve this problem :/ Please help
Sorry I should have been a little more descriptive, I have to figure out what the unknowns are, as in x1, x2, a1 and a2. I can easily do it if I make it a right angled triangle, but for some reason this irregular triangle follows different rules?
You should remember, from geometry, such "congurence" theorems as "SSS", "SAS", "ASA", etc. Generally, if three parts of two triangles are the same then the two triangles are congruent. For others (and even three may not be enough- there is no "ASS" congruence theorem!) there may be non-congruent triangles with the same information, so you cannot calculate the size of the other parts from two parts of a triangle.
