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

Update:

i literally just copied and pasted the question. tell my teacher to learn it, not me.

Update 2:

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.)
