Given quadrilateral ABCD is congruent to Quadrilateral A'B'C'D', What is the measure of B'C'?

Answer 1

Answer: BC=18

Explanation:

because both figures are congruent

BC is equal to B'C'

3x+12=5x+8 we solve the equations by adding and subtracting variables and numbers

3x-5x=8-12

-2x=-4 multiply by -1 and divide by 2

x=2

BC=18

Answer 2

the measure B’C’ is 2 inches
