We know that the building must form a right angle with the ground, so the triangle formed by the ladder, the wall, and the distance between the base of the ladder and the wall is a right triangle. We can use the Pythagorean theorem to find the distance the ladder is from the building.
a^2 + b^2 = c^2
We know that the ladder is the hypotenuse because it is opposite the right angle.
a^2 + b^2 = 20^2
Substitute the length of the other side and solve.
a^2 + 17^2 = 20^2
a^2 + 289 = 400
a^2 = 111
The distance from the wall to the bottom of the ladder is the square root of 111 or approximately 10.5357 feet
The answer is the third one because it describes what they want
B 16 miles an hour
Hope this helps

we know that
If four people write the number zero, then the average will be
Answer:
2
Step-by-step explanation:
parallel lines have same slope.
y = 2x + 5
y = mx + b
m is the slope
b is y-intercept
