<PRE><B>Question 67951</B>
Draw the picture of the isosceles triangle.
The two equal angles are each 7x and the vertex angle is x.
The sum of the angles of a trianble = 180 degrees
----------
EQUATION:
7x+7x+x=180
15x=180
x=12 degrees
The vertex angle = 12 degrees
Each of the base angles is 7x= 84 degrees.
