Answer:
Step-by-step explanation:
x^2=20
just square both sides and u get
x = 4.472135955
7 x 500,000 = 3,500,000.
The towns are 3,500,000 units apart (I don't know what the cm were scale too, sorry.)

Answer:

Step-by-step explanation:
Please refer to the attached diagram. (Apologies if the shading or resolution is a bit off.)
So, we want to find θ.
Since we formed a right triangle, we can use right triangle ratios.
We know the measure of the adjacent side to θ and the hypotenuse.
Therefore, we will use the cosine ratio:

The adjacent side is 2 and the hypotenuse is 15. By substitution:

Now, we will take the inverse cosine of both sides. So:

Use a calculator. Hence:

The angle between the ground and the ladder is about 82.34°.
