I confuse with it also... But I think the degree we get from inverse sine should be sum of base angles, so we can get A using deduction of the sum from 180...Just my opinion, I have no idea with it
i might be late but i think its because as Eddie said, A looks/is obtuse and 30 ish isn't obtuse. We take away 180 as a way to find a, trig functions can have different inputs resulting in the same output which is whats happening here.
Do you remember how, in the previous videos, a single trigonometric equation can have more that one answer, depending on its domain? Well, that's the same here. With a range from 0
Best Math teacher EVER
actual legend
Amazing. Just amazing. Wish I had a teacher like you!
So intellegent maths teacher...
This man out here saving lives 🤩 thank you so much
Simple bt logical explanations
Great math teacher
Just started this topic today and this helped so much 😄❤. Really appreciate it. Thank u 😢❤
Thank you so much! I learned a lot! I finally understood that the sin of your obtuse is the same as the sin of its supplement
Excellent description ❣️❣️❣️
to clarify: this tidbit only applies when solving for that obtuse angle, not when going from obtuse angle to opposite side, correct?
my diagram seems identical with urs, but I still can't find the correct answer.
man like eddie
wow this saved my ass
wtf he should be more popular lmaoaaoaoao
this little problem has confused me for a while
Ayo thank youuu
Legendd
I have know idea what I just learneded 😬
sir, why does uh subtract the answer with 180?

if you look on a sine, cos or tan graph, many values of these angles have many different solutions.
