Answer: 21°
Step-by-step explanation:
Since angles DAE and CBE are inscribed on arc AC, they r equal
Hence angle CBE = 42°
So angle DAE = 42/2 = 21°

Line Graph :
Graphs are visual displays of the data that have been gathered. Its goal is to visualize numerical data in a tangible way so that it may be quickly, simply, and clearly understood. A line graph is a special type of graph that is frequently employed in statistics. It shows how one quantity has changed in relation to another. For instance, we may use this graph to illustrate how the cost of various chocolate flavors fluctuates. Typically, a two-dimensional XY plane is used to plot this variation. A graph is said to be linear if it can represent the relationship between any two measurements by a straight line. Consequently, a line graph is often known as a linear graph.
