Answer:
Ellen is 8 Ft. and 5 In. away from Alice .
Explanation:
By connecting the people like dots , you'd create a right triangle . The distance between Ellen and Alice would be the slant height .
To find the slant height , you could use the formula stated below .
Formula: A^2 + B^2 = C^2 .
A and B represent the distance between Porter between Ellen , as well as the distance between Porter and Alice . C represents the slant height , or how far Ellen is from Alice .
Substitute the variables with the given information and solve .
Substitution: 8^2 + 3^2 = 73 .
Simplify the final value by finding the square root of it .
√73 = 8.54400374532
As stated in the question , you should round the final value to the nearest tenth if necessary .
8.54400374532 ( Rounded ( Tenth ) = 8.5 Ft.
The rounded value would be 8.5 feet .
