Question 1008855
Those were the angle measures.  If segments BA and BC are congruent, then this means angle C is congruent to angle A, so both these angles will be 3x+5.  Why?  You just described isosceles triangle.  Angle C is congruent to angle A.


Sum of the interior angles of the triangle is 180 degrees.
{{{3x+5+3x+5+2x=180}}}
Solve for x.
