Trigonometry question?
Suppose cos β=B for some angle in the first quadrant.
How could you find another angle γ where cos γ=B
How could you find another angle δ where δ=-B
i’m not talking a test but my teacher just didn’t explain this well
i literally just copied and pasted the question. tell my teacher to learn it, not me.
and getting other people to answer isn’t the worst thing in the world, because it wasn’t the perfectly correct answer. you aren’t the only person in the world. thanks anyway ( for not much at all)

You asked this question two days ago, and I gave a perfectly correct answer.
This time you typed an error into the question, by omitting "cos" in the line about -B.
Anyway, the "other angle gamma" is MINUS BETA.
The "other angle delta" is PI MINUS BETA.
(Do learn the Greek alphabet, which I can't type.)
