Question

What is the value of x?There are two triangles, triangle ABC and triangle DEF. Side AB is congruent to side DE, side AC is congruent to side DF. Angle CAB is congruent to angle FDE. The length of the side BC is (x-4).

Answer 1

Answer: x=23

Explanation:

Answer 2

As the given triangles are congruent and also,

it is given that,

AB = DE

AC = DF

so,

the third will also be congruent.

so,

BC = AE

x - 4 = 19

x = 19 + 4

x = 23

thus, the answer is x = 23
