Solve for side AC

nnesha · Answer

$$\rm sin \rm \theta = \frac{ opposite  }{ hypotenuse  }~~~~ \cos \theta = \frac{ adjacent  }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent  }$$

which function you should use to find x ?

anonymous · Answer

TANGENT! :D

nnesha · Answer

you need hypotenuse

nnesha · Answer

you have to find AC which is hypotenuse of right triangle 
given is adjacent

anonymous · Answer

? I really suck at this so please be patient with me. I am math disabled so.

nnesha · Answer

actually i have to go.
otherwise i can wait for 'n hour  :=)

nnesha · Answer

you should have one angle and one side to find 3rd one 
given is adjacent asking for x which is hypotenuse 
so apply cos function $$\rm  cos 35 = \frac{ adjacent }{ hypotenuse  }$$

    $$\rm  cos 35 = \frac{ adjacent }{ hypotenuse  }$$  
$$\cos 35 =\frac{ 15 }{ x}$$
use calculator for cos 35 degree and then solve for x that's it.
