Question

In the accompanying figure, ABCD is a square, AB = 5x-10 and BC= 2x+20. find the value of x.

Answer 1

Answer:

10 units, hope this helps you

Answer 2

Step-by-step explanation:

x = 10

Explanation:

A square is a quadrilateral in which all sides are equal.

We are given that:

ABCD is a square

AB = 5x - 10

BC = 2x + 20

Since we're talking about a square, therefore:

AB = BC

5x - 10 = 2x + 20

5x - 2x = 20 + 10

3x = 30

x = 30/3

x = 10

Now, we can check our solution:

AB = 5(10) - 10 = 40 units

BC = 2(10) + 20 = 40 units

We can see that both sides are equal

Hope this helps :)
