Question

In the following triangle, Theta=60. Find the value of the angle B1 and B2 which solve this ambiguous case

Answer 1

I know that we have to use law of sines
So
sin60/12.3=sinB/13
but, I tried solving this way and I came up with .9 something
which doesn't satisfy the angle.

Answer 2

use degrees mode on your calculator

Answer 3

It is in degrees

Answer 4

Im getting .9153114024
and if I take sin inverse I get
B=66.93
Oh I think I got it
so then 180-66.93=113.07

Answer 5

so b1=66.93
and B2=113.07
