    obviously its math so can you please just do the problem

    Please note that we don't do students' homework for them. Be sure to go back into your textbook or use a good search engine.

    Once YOU have come up with attempted answers to YOUR questions, please re-post and let us know what you think. Then someone here will be happy to comment on your thinking.

    first you have to find the angles cosA and
    SinB using pythogoras theorem. Then using the property expand Sin(A+B)and then substitute the given values. similarly do the same for cos(A+B) and find the quadrant in which A+B lies. That's it!!!
