I have had some question on trig and i could easily find the lines like e.g. whats the size of A-B
However when im doing this i either have to do SIN the angle ,TAN thhe angle,COS the angle.
But what happens if there is no angle.
This is what i do..
Firstly lets say
the angle is called "alpha" and we are using tangent aand opposite,
so we use TAN
next i did is
TAN "alpha" = lets say the sides are 6 which is the opposite and 3 the tangent
all i did was TAN "alpha" = 6/3
Now i did this on my calculator.
INVERSE TAN 3
iam shure i did everythign correct apart from last part so can someone explain please.
