What is the value of x from the below figure?
3, 4, 6, 8

Solution:

We know that the figure is a rectangle as the corner angles are 90.

From the properties of a rectangle, opposite sides are equal

So, 10 + 2x = 18

2x = 18 - 10 = 8

x = 4

The value of x is 4.

What is the value of x from the below figure? 3, 4, 6, 8

Summary:
