The measure of the angle BAC is 72degrees
We have given that the
angle B=108 degrees and angle C=60 degrees.
We have to determine angle A
In parallelogram
The sum of the two angles is 180 degrees.
Therefore we get,
angle A+ angle B=180 degrees
angle B=108 degrees
angle A +108=180
angleA=180-108
angleA=72 degrees.
Therefore the measure of the angle A is 72degrees
