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?

Congurent when applied to two figures means all corresponding linear
dimensions and angles are equal.
Dot quite the same as equal; as figure and its mirror image may not be
"equal" as in indistingushable, but they are still congruent.

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....
2x-10=3x-40
-x=-30
x=30
angle c= 2(30) -10
angle c = 50 degrees
