If quadrilateral J K L M is congruent to quadrilateral C B D A, which pair of sides must be congruent

SInce we don't know the exact shape of the quadrilateral we only know that J=C, K=B, L=D, M=A.

Step-by-step explanation:

This is because the letter order helps to define which sides are congruent to each other! I hope this helps!

the answer is side JK is congruent to side CB

Step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
