Answer:
x=1
Step-by-step explanation:
-31 - 4x= -5 - 5 (1+5x)
-31-4x=-5-5-25x
Separate the different variables and solve.
-31+5+5=4x-25x
-31+10=-21x
-21=-21x
x=1
So the hypotenuse is the ladder's length, which is 6m, and the base of the 'triangle' is 1.5m. Therefore, you do 6^2 - 1.5^2 = 36 - 2.25 = 33.75. Then, you just square root it to get 5.80948m. Hope this helps!
