Step-by-step explanation:
If you are given one interior angle of an isosceles triangle you can find the other two. We know that the interior angles of all triangles add to 180°. So the two base angles must add up to 180-40, or 140°. Since the two base angles are congruent0 (same measure), they are each 70°
