Answer:

x ≈ 29.1

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos31° = \frac{adjacent}{hypotenuse} = \frac{x}{34} ( multiply both sides by 34 )

34 × cos31° = x , then

x ≈ 29.1 ( to the nearest tenth )

If a triangle equals 180 that means 34+31=65 then subtract that from 180 so you do 180-65=115 and then that means 115 is your answer

<u>Answer:</u>

Planet A is inner  

Planet A is Mars

Planet B is Outer

Planet B is Uranus

<u>Solution:</u>

We know that the inner planets are the planets which are close to the sun. They are relatively small, mostly rocky composition, and have few or no moons.

On other hand, the outer planets are the planets which are far away from the sun. They are mostly huge, ringed, gaseous and have several moons.

In the given problem,  

Planet A has rocky mantle and iron core, less no of Moons and no rings, also due to 96% of carbon dioxide, 3% nitrogen and 1% other gases this is denser, and Hence Planet A is inner planet. As the distance from the sun is 1.5 AU and no of moons are 2, hence Planet A is Mars.

On the other hand, Planet B is gaseous with hydrogen and helium gas, hence it is also denser and it has large no of moons and faint rings. So Planet B is Outer planet. As the distance of the planet is 19.22 AU and has 27 moons, hence Planet B is Uranus.
