    Given that,

    The angles in a triangle are represented by x, x+10, and x+50.

    We had to,

    find the measure of the largest angle.

    Let’s start to solve,

    → x + (x+10) + (x+50) = 180°

    → x + x + x = 180° (-50 -10)

    → 3x = 180° -60

    → 3x = 120

    → x = 120/3

    → x = 40°

    Then the value of x + 10,

    → x + 10

    → 40 + 10

    → 50°

    Then the value of x + 50,

    → x + 50

    → 40 + 50

    → 90°

    The measure of the largest angle is,

    → D. 90 degrees

    Hence, option (D) is correct answer.
