If abc dec, what is the value of x? x = 8 x = 5 x = 4 x = 1 x = 2

Option D. x = 1

Step-by-step explanation:

If the two triangles Δ ABC and ΔDEC are similar then there corresponding sides will be in the same ratio.

Now using this theorem in these triangles

Now it has been given

AB = (4x - 1)

BC = 4

EC = 4

DE = x + 2

By putting these values in the formula

We cross multiply on both the sides

(4x - 1) = (x + 2)

4x - x = 1 + 2

3x = 3

x = 1

Option D. x = 1 is the answer.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
