ANSWER

m∠BAD = 22°

EXPLANATION

By the angle addition theorem, the sum of the measures of angles BAD and DAC is equal to the measure of angle BAC,

[tex]m\angle BAD+m\angle DAC=m\angle BAC[/tex]

Replace the known values,

[tex]m\angle BAD+68\degree=90\degree[/tex]

Solving for m∠BAD,

[tex]m∠BAD=90\degree-68\degree=22\degree[/tex]

Hence, the measure of angle BAD is 22°.
