    125°

    Step-by-step explanation:

    Supplementary angles sum to 180°

    let one angle be x then the larger angle is x + 70, thus

    x + x + 7 0 = 180

    2x + 70 = 180 (subtract 70 from both sides)

    2x = 110 (divide both sides by 2)

    x = 55

    Hence

    larger angle = x + 70 = 55 + 70 = 125°
