Answer:

  • B. 100 feet

Step-by-step explanation:

We are looking for the length of the hypotenuse of the 45° right triangle with side of 70.7 ft.

We know the equation:

  • h = s√2, is the length of the hypotenuse and side s

Substitute and calculate:

  • h = 70.7*√2 = 99.98 ≈ 100 ft

Correct choice is B
