    Answer:

    145

    Step-by-step explanation:

    So lets recall what a supplementary angle is. A suppelemenatry angle is  two angles that make up 180 degrees.(half circle)

    This is different from a complenenary angle with is two angles that make up 90 degrees(quarter circle)

    Ok, so we can write the equation for the supplementary angle as:

    35+b=180

    Lets subtract the angle we knwo from both sides:

    b=145

    Now we know that B(second angle) must be equal to 145 degrees.

    Hope this helps!
