BAIf m/BAC = 90°, and m

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°.
