OpenStudy (darkbluechocobo):

\[A=\sin^{-1}\frac{ 2.2\sin40 }{ 1.7 }\]

OpenStudy (rational):

good, find the value in degrees maybe

OpenStudy (darkbluechocobo):

56.3

OpenStudy (darkbluechocobo):

180-40-56.3

OpenStudy (darkbluechocobo):

C=83.7

OpenStudy (darkbluechocobo):

well C1=83.7

OpenStudy (darkbluechocobo):

How would you find C2?

OpenStudy (alekos):

C2/sin83.7=2.2/sin56.3

OpenStudy (rational):

hey

OpenStudy (rational):

did you get A = 56.3 ?

OpenStudy (rational):

you must get two values for A that are less than 180

OpenStudy (rational):

A = 56.3, 123.7

OpenStudy (rational):

the corresponding values for C would be C = 83.7, 16.3
