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°.
Answer:
pretty sure its the 2nd, 3rd, and 5th one

Answer:
25%
Step-by-step explanation:
There are 20 minutes between 10 and 30 and 5 minutes between 10 and 15 so you need to find 5% of 20 (5/20 x 100) which is 25%
All are congruent segments. Beacuse congruent segments are two segments that are equal in length.
