Answer:
The identity of an element is determined by the number of protons. One can't adjust the number of protons without changing the identity of the element. By adding a proton, the atomic number builds up by one and the element identity changes. The number of neutrons can be adjusted to create isotopes. Number of electrons can be altered to create ions.

I'm assuming you're comparing two triangles? If not, then this is probably wrong.
Triangle = 180 degrees
180 divided by 3 = 60 degrees
since ∠1 ≅ ∠2 ≅ ∠3, each angle equal 60 degrees
∠4 ≅ ∠5
m∠4 = m∠3 + 10
m∠3 + 10 = m∠5
we know that m∠3 is 60 degrees.
60 + 10 = 70, so m∠5 is 70 degrees
70 degrees is the answer.
