Triangle ABC is congruent to triangle A'B'C'. If angle C is represented by
2x - 10 and angle C' is represented by 3x - 40, find the measure of angle C.
NOTE: Does the word congruent mean the same as equal?
if it is congruent that means corresponding parts of the triangle are congruent (equal if you like)
so angel c is congruent to angle c'. so....
angle c= 2(30) -10
angle c = 50 degrees
