if an angle has 40DEGREES and 80 dgrees what is the missing number?

  • math -

    Umm I think Its 60, if I know what you mean, if its a triangle. ( learned that if you press alt and 0176, it will give you the degree sign.

    A triangle is 180°.
    You take 40+80, and get 120.
    So then you take 180-120, and get 60°.

  • math -

    If your figure is triangle sum of angles must be 180°

    40°+80°+x=180°

    120°+x=180°

    x=180°-120°

    x=60°
