Answer:
Value of ∠N = 135°
Explanation:
Given that;
Quadrilateral KLMN is a parallelogram
Value of ∠K = 55°
Find:
Value of ∠N = x°
Computation:
We know that;
Quadrilateral KLMN is a parallelogram
We know that in a parallelogram, sum of co-interior angle is 180
So,
⇒ ∠K + ∠N = 180°
⇒ 55 + x = 180
⇒ x = 180 - 55
⇒ x = 135
So,
⇒ Value of x = 55
Value of ∠N = 135°

Some birds are nomadic in winter, others spend the colder months in the southwestern part of the continent or in the Mediterranean region. Geographical conditions determine several main routes. The Alps are an important barrier to migratory birds. About 150 travel westward and southwestward; others travel southeastward.
