@Luigi0210  May you be able to help me? :)

So it's this? 

|dw:1433441809145:dw|

anonymous · Answer

Yes!! Without the a

luigi0210 · Answer

Okayyyy, if you know your triangles, you should know that 5-12-13 is a special triangle like 3-4-5. So we can just replace a with 5. 

In order to find x, we could do either the sine, cosine, or tangent, your choice since we have all the sides.

Im going to go with tan

luigi0210 · Answer

Alright! So tangent is: $\large \tan\theta=\frac{opposite}{adjacent} $ 


So for your triangle: 
|dw:1433442229985:dw|

So $\large \tan x=\frac{5}{12} $ 
Make sense?
