Question

1. Find the measure of angle B and C?

The image shows a geometric diagram involving a triangle and a straight line. Here's a detailed explanation: **Diagram Description:** - There is a straight line, represented by points A, D, and B. Point D is between points A and B on the line. - From point D, a triangle is formed with vertices D, B, and C. **Line Segment:** - The segment extending from point A through D to B forms a straight angle. - The angle between segments AD and DB is marked as \(120^\circ\). **Triangle:** - The triangle is labeled as \(\triangle DBC\), with vertex C above point D. - The angle at vertex C formed by lines DC and BC is labeled with the expression \(15x + 5\). - The angle at vertex B of the triangle is labeled with the expression \(22x + 4\). This geometric setup illustrates the relationship between angles in a triangle and a straight line, ideal for exploring angle sum properties and linear equations involving unknowns like \(x\).
