Answer:
The value of x is 120°.
Explanation:
Given that 3 identical square form a triangle in between. So this triangle has an identical angle so it is :
180° ÷ 3 = 60°
Next, this squares have an identical angle which is :
360° ÷ 4 = 90°
As you look carefully at the diagram, in the edges of triangle, there is a complete circle which is 360°. SO in order to find x, you have to substract 90° and 60° from 360° :
x + 90° + 60° = 360°
x = 360° - 90° - 90° - 60°
x = 120°
