Answer:
BC ≈ 8.9 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos36° = 
= 
= 
( multiply both sides by 11 )
11 × cos36° = BC , then
BC ≈ 8.9 ( to the nearest tenth )

Answer:
Option B. 2376 Square feet
Step-by-step explanation:
The following were obtained obtained from the question:
Base (B) = 24ft
Length (L) = 40ft
Height (H) = 9ft
Slant height (S) = 15ft
Surface Area (A) =?
The surface area (A) for triangular prism is given below:
A = BH + 2LS + LB
Where:
B is the Base
L is the Length
H is the Height
S is the Slant Height
A is the Surface Area
Using the above equation, the surface area can be obtained as follow:
A = BH + 2LS + LB
A = (24x9) + (2x40x15) + (40x24)
A = 216 + 1200 + 960
A = 2376 ft2
