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 $\boxed {105}\degree$

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 $\boxed {85}\degree$

Answer 2

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