Question 1008855: In triangle ABC, measure of angle A = 3x+5, measure B = 2x, and measure c is left blank. Solve for x and find the measure angle C. Answer by josgarithmetic(39616) (Show Source):
You can put this solution on YOUR website! 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.
Solve for x.
