Question

BAIf m/BAC = 90°, and m

Answer 1

m∠BAD = 22°

Step-by-step explanation

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

`m\angle BAD+m\angle DAC=m\angle BAC`

Replace the known values,

`m\angle BAD+68\degree=90\degree`

Solving for m∠BAD,

`m∠BAD=90\degree-68\degree=22\degree`

Hence, the measure of angle BAD is 22°.
