The answer is C. I am sure this is correct
Given parameters:
Each interior angle = 150°
Unknown:
The number of sides of this regular polygon = ?
Solution:
To find the sum of internal angles of a regular polygon, we use the expression below;
(n - 2) x 180 = sum of internal angles of a polygon
n is the number of sides,
Also, the sum of the internal angles of a polygon = number of sides x internal angles;
So;
(n-2) x 180 = 150 x n
Solve for n;
180n - 360 = 150n
180n - 150n = 360
30n = 360
n = 12;
Therefore, the number of sides is 12
The correct answer is 4) They have ring systems.
Explanation:
Jovial planets are also known as Giant planets, they include Jupiter, Saturn, Uranus and Neptune, these planets are classified as Giant planets because they are massive although they are composed mainly of gas and light materials. Additionally, most of this planets have one or more moons and all of them have ring systems which are rings made of particles, dust, debris, ice and other materials that are placed around the planet and orbit it, although only the ring system of Saturn is visible and because of this it is the best known. Thus, the statement that describes Jovian planets is "They have ring systems".
