    The measures of the angles are 65° and 80°

    Step-by-step explanation:

    One of the angles is 35°

    We know that the other two angles have a difference of 15°

    With this knowledge we can write an equation.

    2x symbolizes the two angles

    +15 symbolizes the difference between the two angles

    145 = 2x + 15

    145 - 15 = 130

    2x = 130

    x = 65

    65 is the size of one of the angles.

    Next, we add 15 to 65 and we get 80

    80 is our second angle
