Answer:
Step-by-step explanation:
Use a proportion to solve for the missing side length - a/c = b/d.
4/2 = 6/s cross-multiply
4s = 12 divide by 4
set up a ratio to find the length:
15/12 = DE/16
cross multiply the 15 & 16:
15 * 16 = 240
divide that by 12 to get DE
240 / 12 = 20
DE = 20
Answer: 864 ft

Step-by-step explanation: You can look up the formula and use it
side length a =
12
side length b =
96
side length c =
16
height h =
14
X + 7.4 = 49.8
x = 49.8 - 7.4 //Take away 7.4 from both sides
x= 42.4
