Answer:
4.9 feet
Step-by-step explanation:
First, we need to determine the height of the building using the following:

Where
H = Height of the building
L = Length of the first ladder = 20ft
B = Distance from the base of the building = 10ft
So, we have:





Next, is to determine the distance of the new ladder from the base of the building (B) using Pythagoras theorem using:

Where
--- Length of the second ladder
----- Height of the building
So, we have:




Solving for B2, we have:


Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite. When working with the graph of y = f (x), replace x with -x. Reflection in y = x: When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places.
Answer:
6 cm
Step-by-step explanation:
To find the range take the largest number and subtract the smallest number
The largest number is 141 and the smallest number is 135
141 - 135 = 6 cm
