Answer:
I am not sure but A.69° . anything else but wrong answer sorry
Step-by-step explanation:
and thanks for you free points .
Assuming

. We have Lagrangian

with partial derivatives (set to 0)[/tex]





Solving this system of linear equations yields

and

as the sole critical point, which in turn gives a maximum value of

.
Using the Pythagorean theorem:
6^2 + X^2 = 14^2
36 + x^2 = 196
X^2 = 196-36
x^2 = 160
x = SQRT(160)
x = 4 SQRT(10)
Or as a decimal:
x = 12.65 inches
Step-by-step explanation:
14/17 is 0.82352941176
To the nearest tenth is 0.8
