Answer:
nwm
Step-by-step explanation:
Answer:x = 75
Step-by-step explanation:y=105 - 5 = 100 ft
z=125 ft
dz/dt=2 ft/sec
by using Pythagorean Theorem, we find x
x^2 + 100^2 = 125^2
x = 75
Isolate the variable by dividing each side by factors that don't contain the variable.
-6x-15+15=4x+35+15
-6x=4x+50
(Subtract 4 on both sides)
-10x=50
(Divide by 10 on both sides)
x=5
