The two angles are supplementary angles which means they need to equal 180 degrees when added together.
4x + x = 180
5x = 180
Divide both sides by 5:
x = 180/5
x = 36
The answer is 24
Explanation
7•8 is 56
And 3•8 is 24
It would be 11 + 12 = 23 atomic mass units.
(electrons have about a mass of 5.489×10−4<span> atomic mass units, so their mass would be negligible in this calculation).
