5. Johannes Kepler published his third law of planetary motion in 1619. The third law is a mathematical equation to
find the amount of time that a planet takes to orbit once around the Sun based on how far away the planet is from
the Sun.

Ops Third Law is: T = 0.2R2, where T is the time for a planet to go once around the Sun in Earth days (i. e.
24 hours), and R is t.
.) and R is the distance between the planet and the Sun in millions of kilometres. For example, Mercury
58 million kilometers from the Sun, therefore R = 58 for Mercury.
The distance between Mars and the Sun is 228 000 000 km. How many days does it take Mars to orbit
once around the Sun? How many “earth years" is it?

b) It takes the former planet Pluto 248 years to orbit once around the Sun. How far away is Pluto?

c) Use the equation to determine Earth's distance from the Sun.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
