Hi all

question on triangometry .

Attachment 19326Attachment 29044

I know solve this quetion put are we saying :

tan = 6/6.7 = 0.8955

or tan =6/6.7 =0.0156

I don't n did we take tan or direct divide 6/6.7 = 0.8955

I want your help please .

Fisrtly, you cannot have tan by itself. You have to have tan of something.

You know that the tangent rule for a right angle triangle is $\displaystyle \tan{\theta} = \frac{opposite}{adjacent}$

That means $\displaystyle \theta = \tan^{-1}\left(\frac{opposite}{adjacent}\right)$

Do you understand? - Oct 14th 2010, 01:38 AMr-soy
