Answer:
Length of the pole = 12.2ft
Step-by-step explanation:
Hello,
According to your description, the pole against a wall of height 7ft and the distance between the base of the pole to the wall is 10ft.
See attached document for better illustration.
To solve this problem, we'll have to make use of pythagorean theorem
According to pythagorean theorem,
X² = y² + z²
X = ?
Y = 10ft
Z = 7ft
X² = 10² + 7²
X² = 100 + 49
X² = 149
X = √(149)
X = 12.2ft
The length of the pole is 12.2 ft
Unfortunately, the length of the pole does not corresponds with any of the answers above, but this is actually the right answer.
Good luck
