Answer:
Do using Pythagoras theorem... Also before doing a question of height and distance always try to make the figure
Step-by-step explanation:
Use the two triangles ABC and ABD to first get the base and find the height of the ladder
Set the two equal to each other and solve for x
-2x+1 = -2x²+1
-2x= -2x²
x=x²
x²-x=0
x(x-1) =0, so x is either 0 or 1
two solutions, namely (0,1) and (1,1)
So, 4.01 is less than 4.1. Think of it as 4.10 and 4.01, 1 is less than 10. One you could have put is 4.101, because it is more than 4.1 and less than 4.11
