Answer:

  ∠ABC = 56°

Step-by-step explanation:

The equilateral triangle is irrelevant and can be ignored.

The angle marked 62° is one of the base angles of the isosceles triangle. The other base angle (at D) will have the same measure. The sum of angles in a triangle is 180°, so you have ...

  ∠A +∠D +∠B = 180°

  62° +62° +∠B = 180°

  ∠B = 180° -124° = 56°

The measure of ∠ABC is 56°.
