Answer:

x = 11, y = 8

Step-by-step explanation:

ΔABC and ΔFDE are congruent by the postulate SSS

Equate the congruent sides in the 2 triangles

BC = ED, that is

x + 3 = 14 ( subtract 3 from both sides )

x = 11

-------------------------------------

DF = AB, that is

x - y = 3 ← substitute x = 11

11 - y = 3 ( subtract 11 from both sides )

- y = 3 - 11 = - 8 ( multiply both sides by - 1 )

y = 8

Answer:

The value of x is 11 and the value of y is 8.

Step-by-step explanation:

It is given that ∆ABC and ∆FDE are congruent.

The corresponding parts of congruent triangle are congruent.

[tex]AB=FD[/tex]                       (CPCTC)

[tex]3=x-y[/tex]                 .... (1)

[tex]BC=DE[/tex]                       (CPCTC)

[tex]x+3=14[/tex]

Subtract 3 from both the sides.

[tex]x=14-3[/tex]

[tex]x=11[/tex]

The value of x is 11.

Put x=11 in equation (1).

[tex]3=11-y[/tex]

Add y on both the sides.

[tex]3+y=11[/tex]

Subtract 3 from both the sides.

[tex]y=11-3[/tex]

[tex]y=8[/tex]

The value of y is 8.
