Answer:
See below
Step-by-step explanation:
The measure of all the arcs can be obtained by using 'Central angle and its corresponding arc theorem'.
1. The measure of arc AD is
2. The measure of arc ABC is
3. The measure of arc ADB is
4. The measure of arc BD is 
Y=-3/5x+3
3/5x+y=3
3x+5y=15
Final answer: 3x+5y=15
