Agreement or concord happens when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some grammatical category "agree" between varied words or parts of the sentence.

Answer:
Since the sum of any two consecutive angles of a parallelogram is 180
o
. Therefore,
∠A+∠D=180
o
and ∠A+∠B=180
o
Now, ∠A+∠D=180
o
∠A+115
o
=180
o
∠A=65
o
and, ∠A+∠B=180
o
65
o
+∠B=180
o
∠B=115
o
Thus, ∠A=65
o
and ∠B=115
o
.
