The missing angle is 53 degrees (82+45=127) (180-127=53)
Answer:
Step-by-step explanation:
One unit up: y = x + 1
One unit down: y = x - 1
One unit to the left: y = x + 1
One unit to the right: y = x - 1
If it is the most common isotope and of Carbon and it is not an ion, you can conclude that it has 6 protons and 6 electrons.
Here, as the sides are equal, middle line would be exact half then the longer (bottom) side of the triangle.
48 = 2(3x)
6x = 48
x = 48/6
x = 8
In short, Your Answer would be Option D
Hope this helps!
