Answer:
The measurement of the second angle is [tex]120\°[/tex]
Step-by-step explanation:
we know that
If two angles are supplementary
then
their sum is equal to [tex]180\°[/tex]
Let
x------> the measure of the second angle
so
[tex]x+60\°=180\°[/tex]
Solve for x
[tex]x=180\°-60\°[/tex]
[tex]x=120\°[/tex]
