Question 1147448
.
<pre>

If the angle measure is x, then the supplementary angle is  (x+158) degrees, according to the condition.


It gives you an equation for the angle measure x


    x+158 = 180 - x.


Hence,


    2x = 180 - 158 = 22.

     x             = 22/2 = 11 degrees.


<U>Answer</U>.  The angle is 11 degrees; the supplementary angle is  180-11 = 169 degrees.

Solved.
