A
A 56°
B 340
C 68°
D 170

Answer 1

68°

Explanation:

Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.

`\therefore m\angle DBR = (1)/(2) * m\angle DAR\\\\</p><p>\therefore 34\degree = (1)/(2) * m\angle DAR\\\\</p><p>\therefore 34\degree * 2= m\angle DAR\\\\</p><p>\therefore 68\degree = m\angle DAR\\\\</p><p>\therefore m\angle DAR=68\degree`
