Answer:

m∠DAB = 91 degrees

Explanation:

Total degree of a parallelogram = 360

m∠CDA = m∠ABC

Let x represent m∠DAB & m∠DCB

m∠CDA + m∠ABC + m∠DAB + m∠DCB = 360 degrees

89 + 89 + x + x = 360 degrees

Add 89 + 89

178 + x + x = 360

Subtract 360 - 178

x + x = 182

Divide 182 by 2

x = 91 degrees

so the m∠DAB = 91 degrees
