Soruda görsel içerik var: A large triangle ABC is depicted with A at the top, B at the bottom left, and C at the bottom right. Inside, there is a point D connected to B and C, forming the triangle BDC. The line segments BD and CD are angle bisectors of angle B and angle C, respectively. These are indicated by matching marks: two parallel lines on the two equal parts of angle B and two dots on the two equal parts of angle C. The interior angle m(BDC) is labeled as 110 degrees. The interior angle at vertex A is labeled as x.
