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
`\boxed {105}\degree`

2. The measure of arc ABC is
`\boxed {205}\degree`

3. The measure of arc ADB is
`\boxed {190}\degree`

4. The measure of arc BD is
`\boxed {85}\degree`

it adds up to 360.
35 + 50 + 105 = 190
360 - 190 = 170
