I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75

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
![C^= A^2+B^2\\\\C= \sqrt{A^2+B^2}](https://tex.z-dn.net/?f=C%5E%3D%20A%5E2%2BB%5E2%5C%5C%5C%5CC%3D%20%5Csqrt%7BA%5E2%2BB%5E2%7D)
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
