105°
105°
✓
Answer
Place the vertex of 45° of the set-square and make angle of 90° by drawing the rays BD and BC as shown in the figure
Now, place the vertex of 30° of the set-square on the ray BS as shown in the figure and draw the ray BA The angle so formed is 150°. Therefore, $\angle\text{ABC}=150^{\circ}$
