Question 1169332
.
<pre>

The vertex angle is 2x;


each of the two base angles is 5x.



The sum of the angles equation is

    2x + 5x + 5x = 180  degrees,   or


        12x      = 180,

          x      = 180/12 = 15.



<U>ANSWER</U>.  The angles are  2*15 = 30 angles (the vertex);

         5*15 = 75 degrees  (each of the two base angles).

Solved.
