Answer:

d^2 = 30^2 + 12^2

e^2 = d^2 + 8^2

e^2 = 30^2 + 12^2 + 8^2

e = √(30^2 + 12^2 + 8^2) = 33.3 ft

Answer:

33.3 feet to the nearest tenth.

Step-by-step explanation:

WE first need to find the length of the diagonal (d) across the bottom of the room.

d^2  = 30^2 + 12^2 = 1044.

Now applying Pythagoras theorem to the triangle whose hypotenuse (h)  is the path of the spider:

h^2 = d^2 + 8^2

= 1044 + 64

= 1108

h = √1108

= 33.3 feet.
