Find the perimeter of the polygon
pychu [463]

Answer:

Answer 60

Step-by-step explanation:

The distance from an exterior point to the incircle is equal to the tangent length in both cases.

So the 19 is made up of 9 and 10.

The length of the other portion of the tangent from the end of 19 to the tangent point on the right is also 10.

By a similar argument the lower length of the line to the tangent point is 11.

So you have

9 + 9 + 10 + 10 + 11 + 11

18 + 20 + 22 = 60.

Hello please help thanks
Vladimir79 [104]

Answer:

Oceans and the Sun.

Step-by-step explanation:

Lakes and the sun is also a good answer, but the question is asking which interact the <em>most</em>, which is the ocean and sun.

We can also rule out the moon since it has nothing to do with the water cycle, so the last two options are also wrong.
