Using the concept of linear pair we get the measure of angle a that is equal to 94 degree.
Two lines are given k and m
In the below attached image we can see there are two lines k and m that are intersecting .
lines that intersect meet at a common point.
Here we will use the concept of Linear pair of angles.
When two lines intersect with each other then some angles are formed (opposite angles and adjacent angles).
If the angles are adjacent to each other then the angles are known as linear pair of angles.
Using the property that the Sum of angles of linear pair is always equal to 180 degree -------A
From the figure
86 + a = 180 (From A)
a= 180-86
a= 94
So the measure of the angle a is 94 degree.
