PLEASE HELPP ME !!! What is the length of side x in the triangle below? picture is below
|dw:1398118596929:dw|
use the law of sin
i dont know how to use it
\[\frac{ x }{ \sin(\angle) } = \frac{ 8 }{ \sin(\angle) }\]
thats the equation so far, can you find the value of the angle that is 'across' from the side that has the length of 8?
30-60-90
@DemolisionWolf
yes, those are the interior angles of the triangle that add up to 180, i'm looking for, what is the value of the angle across from this side? |dw:1398119069194:dw|
so wouldnt i use a2=b2+c2
the angle 'across' from side 8 is 60 |dw:1398119190412:dw| do u see how it is 'across'? \[\frac{ 8 }{ \sin(60) } = \frac{ x }{ \sin(\angle) }\] now, can you use the same method i just used to find the 'across' angle value, but now do it for side x?
