please help preparing for test

## 1 Expert Answer

major relations are"

:

sum of 3 angles = 180 degrees or pi radians

with also if you have a right triangle, the other 2 angles sum to 90

then there's the law of sines and cosines

sinA/A = sinB/B = sinC/C

and

c^2 = a^2 +b^2 -2abcosC where C is the angle opposite side c

with those 3 concepts, you can figure out most triangle problems

and any angle problems can usually be broken down into triangle problems

Can you be a little more explicit? Is there a specific relationship (or set of relationships) that you have questions on?
