Answer:
a = 28
b = 87
Step-by-step explanation:
By definition, opposite sides of a parallelogram are equal. So we can set the two expressions equal and solve for a:
a - 10 = 18
a = 28
Also by definition, opposite angles of a parallelogram are congruent. So set those two expressions equal and solve for b:
b + 16 = 103
b = 87
Hope this helps!
