@HWBUSTER00 lol i was a bit slower than u!;-D but here it is!!!

@danielgarcia413 heres the other question! ((;

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

$tanR=\frac{ 21 }{ 20 }$

7. Nnesha

|dw:1433719432687:dw| to find measure of angle R you should know value of two numbers

8. anonymous

$R=\tan^{-1} \frac{ 21 }{ 20 }$

I need to get used to this lol
