<h2>
Step-by-step explanation:</h2>
Let "h" denotes the height of the box.
Length of box is denoted by "l"
and breadth or width of box is denoted by "b"
We are given l=18 ft
b=8 ft.
Also we are given surface area of rectangular box= 496 ft²
As we know that the surface area of box is given by:
i.e.
Divide both side by 2.
on dividing both side by 26 we get:
Hence, the height of the box is:
4 ft.

The two x terms combine, making 8x, and the answer is
Answer:
C 117
Step-by-step explanation:
<2 = 63 vertical angles
<2 = <4 alternate interior angles
<4 + <7 = 180 straight line
