If you tend to obtain your goals, keep this in mind! beneath are one of the answer and question example that you would probably work with to practice and further enhance your understanding and also give you insights that could assist you to preserve your study in school.

## Question:

If ABC DEC, what is the value of x?

x = 8

x = 5

x = 4

x = 1

x = 2

## Answer:

**Answer:**

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.

They could certainly hopefully guide the student solve the question by make use of the questions and answer examples. You could certainly then have a discussion with your classmate and continue the school learning by studying the question to one another.
