Provides a unique set of guidelines that can be applied to any triangle. The guidelines demonstrate a clear understanding of applying the laws of sines and cosines.

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)
