Step-by-step explanation:
Given that,
The length of a ladder, H = 20 feet
The height of the wall, h = 15 ft
We know that,

h is perpendicular and H is hypotenuse
So,

Now using Pythagoras theoerm,

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.

Answer: C.
Explanation:
A New Leash On Life's Graph has: 3, 11, 21, 13, and 4.
The mean: 10.4
No Ruff Stuff's graph has: 1, 9, 16, 16, 8, 1, and 1.
The mean: 7.43.
The slope formula is y2-y1/x2-x1 so 5-(-1) =6 Then. 1-(-1)=2 so 6/2. =3. THE ANSWER IS 3
The values for y are as follows
4.5, 4, 3.5, 3, 2.5, 2
