Audra is looking at a diagram of an oxygen atom. Which particle(s) does she see inside the nucleus? plz help this is like 30% of my grade :)

C: protons and electrons are found in the nucleus.

Step-by-step explanation:

Ok! So all atoms are composed of three basic things, protons, neutrons, and electrons. There are two parts of an atom, the nucleus and the electron cloud that surrounds the nucleus. In the nucleus are the protons and neutrons, and in the electron cloud are the electrons. Therefore, the answer would be C: protons and electrons are found in the nucleus.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
