In parallelogram ABCD, m∠BAC = 40.62°and m∠BCA = 30.96°. What is m∠BAD?
KatRina [158]
The answer is letter a.  m∠BAD = 108.42<span>° 

The solution is as follows:
If </span>m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° -  m∠BCA - <span>m∠BAC
</span>m∠CBA = <span>108.42°
</span>
Since m∠BAD = m∠CBA  due to the parallelogram's property, 
<span>m∠BAD</span> = <span>108.42°.</span>
