chapter 9-1!!!!
in this chapter, we learned how to solvee right angles using SOHCAHTOA. this is a shortcut you use to find the sides of the triangles and even the angles.


S-sine
O-opposite
H-hypoteneuse
C-cosine
A-adjacent
H-hypoteneuse
T-tangent
O-opposite
A-adjacent


Examples: A=90; B=30; c=5; a=13
-first you want to find C. in order to do this you must use SOHCAHTOA.
use sinx=5/13
C=60

-then you want to find b. use sin30=x/13
b=12
