two straight lengths of wire are placed on the ground, forming vertical angles. if the measure of one of the angles formed is 72, what are the measures of the
other three angles? explain your answer.

72, 108, 108

Explanation:

The 2 wires form 2 pairs of vertical angles and the angles add up to equal 360 degrees. Since 1 of the angles equal 72, that means the vertical angle of the angle that equals 72 is also 72 degrees.

72 + 72 = 144

360 - 144 = 216

216/2 = 108

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
