When silicon atoms bond, then silicates form which are minerals in which such elements as potassium, calcium, magnesium and aluminum combine with the silicon atoms to form minerals like feldspars of different types or if it is just silicon and oxygen that bond then it forms quartz.
Okay so you can find the angle by working out the angle in the top right corner of the backwards 'Z' shape. Because there's 180 degrees in a straight line, that top right angle is 180 - 132 = 48.
Now we know that the top right angle is 48, so the angle you're looking for is 48, because they're alternate angles.
That means 3x + 9 = 48. You can find x by rearranging.
3x + 9 = 48
3x = 48 - 9
3x = 39
x = 13.
x is equal to 13.
