  • The image displays a large triangle with vertices labeled B, A, and C, forming the shape B-A-C.
  • The base of the triangle rests on a horizontal line segment, with points B and C marking the endpoints.
  • A vertical dashed line is drawn from vertex A down to the base line segment, intersecting it at point D.
  • This dashed line segment, AD, represents the height or altitude of the triangle.
  • The angle formed at vertex A by the dashed line AD and the side AB is labeled with the expression \text{x}/2.
  • The angle formed at vertex A by the dashed line AD and the side AC is also labeled with the expression \text{x}/2.
  • The interior angles of the large triangle are labeled: the angle at B is labeled \text{x}, and the angle at C is labeled \text{x}.
