Provides a unique set of guidelines that can be applied to any triangle. The guidelines demonstrate a clear understanding of app
Oksi-84 [34.3K]

we can have a triangle  and we know that there are two angles. 

30º and a 45º + 105 =180º angle. applying the sides. 

therefore if we have the whole triangle completed we have a constant triangle. 


so it tell us we can you’se SOH CAH TOA 

we can varrify what kind of triangle we are using. 


for example if we were to use  Sin I would do 


Sin 30/ 2 = sin of 105º/ A = sin=45º/ B


if you would want to solve for  sin 30/2 and sin 105, then we solve. 

 

or Sin 30/2  and Sin 105 as well. 


with your calculator use sin= 30=.5  and use sin 105º a divide by 1.5 on both sides    1.5= A /sin 105º * 1.5   answer would be 3.86.  a is = to 3.86 (Not the answer)
