Step-by-step explanation:
now onto the second one,
now, the extraneous part, I don't see either as extraneous, 3 and 12 do work, however, I take it is referring to the root, so if we nevermind the root has ± versions, and say only assuming the value coming from the root is say positive, then

Answer:
<h2> The distance between Bridget and Alan is 9.48 ft</h2>
Step-by-step explanation:
kindly find attached a rough sketch of their sitting position which forms a right triangle
We can proceed by using Pythagoras therm to solve for the distance between Bridget and Alan which is the hypotenuse
From the problem statement
A, which is the opposite is = 3 ft
B, which is the adjacent = 9 ft
C, is the hypotenuse= ?
Substituting into the expression we have
To the nearest tenth the distance is 9.48 ft
