Question

Can someone prove to me how exactly is the other angle for this is 150???

Answer 1

I solved it up till 30 degrees but then they're saying the "since AC is the largest side"
I don't get it

Answer 2

do you remember your unit circle?

Answer 3

yea

Answer 4

So do you remember that when we have sine of an angle, it can have two values?

Answer 5

yea you minus 30 180
yea I know that but visually I just can't imagine it in this triangle

Answer 6

30 minus from 180

Answer 7

yeah, that's how you get 150 degrees...
If theta = 30, it means that angle ABC and angle ACB would be larger than 30 true?
Since the ANGLE SUM of a triangle = 180 right?
