1) act prep: linear pair angles have measures (6x -9)°and (9x-6)° 1.
sketch and solve for the angle measures. your choices will only have one angle listed.
a) 15° b) 30°c) 11° d) 69°e) 105°

The measure of angles are 69 degree and 111 degree

Solution:

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,

Thus the measure of angles are:

Thus measure of angles are 69 degree and 111 degree

the correct answer is 45x

9×5=45 then add the x
