    Answer:

    65°

    Step-by-step explanation:

    From the question,

    The base angle of an isoceles triangle are equal.

    Let the value of the base angles = x°

    Sum of angle in a triangle = 180°

    ⇒ x°+x°+50° = 180°

    ⇒ 2x°+50° = 180°

    ⇒ 2x° = 180°-50°

    ⇒ 2x° = 130°

    ⇒ 2x°/2 = 130/2

    ⇒ x° = 65°.

    Hence, the size of the other angles is 65°
