30°

Explanation:

`\overline {CA} \cong \overline {BD}... (given) \\</p><p>\therefore \overset {\frown} {CA} \cong \overset {\frown} {BD}\\`

(equal chords intercepts equal arcs)

`\therefore \overset {\frown} {AB} \cong \overset {\frown} {CD}\\</p><p>\therefore m \overset {\frown} {AB} =m \overset {\frown} {CD}\\</p><p>m \overset {\frown} {CD}=30°...(given) \\</p><p>\therefore m \overset {\frown} {AB} =30°\\`
