Given:

Two angles form a linear pair.

The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10°.

To find:

The measure of the smallest and biggest angle.

Solution:

Two angles form a linear pair. The measure of one angle is z.

The measure of the other angle is 2.4 times z plus 10°, i.e.,
2.4z+10^\circ.

We know that if two angles form a linear pair then their sum is 180 degrees.


z+(2.4z+10^\circ)=180^\circ


3.4z=180^\circ -10^\circ


3.4z=170^\circ

Divide both sides by 3.4.


z=(170^\circ)/(3.4)


z=50^\circ

Now, the measure of other angle is:


2.4z+10^\circ =2.4(50^\circ)+10^\circ


2.4z+10^\circ =120^\circ+10^\circ


2.4z+10^\circ =130^\circ

Therefore, the measure of the smaller angle is
50^\circ and the measure of the bigger angle is
130^\circ.
