To solve for the mass defect of the given atom, add up the individual masses of the nucleons, protons and neutrons. In this case, the total mass of the nucleons is solved through 8x(1.0073 + 1.0087) and is equal to 16.128. Subtracting the mass of the intact nucleus which is 15.9994 gives 0.1286. Thus, the mass defect is 0.1286.
Answer:
mZW=144
Angle x= 72 degrees
Step-by-step explanation:
mZW is equal to 144 because 72 times 2 is equal to 144.
Angle x is equal to 72 degrees because angle y and angle x are equal.

Answer:
I think the answer would be C.)
You could factor a 7 out of 7 + 14 to get 7(1 + 2).
This would equal the same thing as 7 + 14, which is 21.
7 * 3 = 21.
21 can be factored like so:
1 * 21 = 21
3 * 7 = 21
