The measure of angles are 69 degree and 111 degree
<em><u>Solution:</u></em>
Given is linear pair angles
The measure of angles are: (6x - 9) degrees and (9x - 6) degrees
A linear pair of angles is formed when two lines intersect.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Therefore,
<em><u>Thus the measure of angles are:</u></em>
Thus measure of angles are 69 degree and 111 degree
