Question

Determine the value of x in the diagram.
x
2x
2x

Answer 1

x = 60

Explanation:

The sum of exterior angles in a rectangle is equal to 360

so to find the value of x we need to use all given values and write an equation:

x + 2x + x + 2x = 360 add like terms

6x = 360 divide both sides by 6

x = 60
