Question

In the diagram, △ABC≅△DEF. Find the values of x and y.

Answer 1

9514 1404 393

Answer:

• x = 5
• y = 20

Step-by-step explanation:

We need x first.

  AB = DE

  12 = 3x -3

  4 = x -1 . . . . . divide by 3

  5 = x

Now, we can find y.

  ∠C = ∠F

  7x +y = 55

  y = 55 -7x = 55 -7(5)

  y = 20
