Answer:

68°

Step-by-step explanation:

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

[tex] \therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree \times 2= m\angle DAR\\\\

\therefore 68\degree = m\angle DAR\\\\

\therefore m\angle DAR=68\degree[/tex]
