Question 1174351
.
An angle measures 12° less than the measure of its supplementary angle. What is the measure of each angle?
~~~~~~~~~~~~~~~~


<pre>
Let x be the angle measure.

Then the measure of other angle is (x+12) degrees, according to the condition.


Since the angles are supplementary, they sum up to 180 degrees

    
    x + (x+12) = 180


Simplify and solve


    2x = 180 - 12 = 168

     x            = 168/2 = 84.


<U>ANSWER</U>.  The angle measure is 84°.  The other angle is  84° + 12° = 96°.
</pre>

Solved.
