    Answer:

    The measure of the other angle is 59°

    Step-by-step explanation:

    Supplementary Angles

    Two angles \alpha and \beta are supplementary when they add up to 180 degrees, i.e.

    \alpha+\beta=180^o

    One notable property is that together they make a straight angle although they don’t have to be together to be supplementary.

    We are given one of two supplementary angles with a value of 121 degrees, we can compute the measure of the other angle, say \alpha as

    \alpha=180^o-\beta=180^o-121^o=59^o

    The measure of the other angle is 59°
