Answer:
-10 =v
Step-by-step explanation:
-13 = v/10 - 12
Add 12 to each side
-13+12 = v/10 - 12+12
-1 = v/10
Multiply each side by 10
-1*10 = v/10 *10
-10 =v
Area (square)=side²
therefore:
side²=200 feet²
side=√(200 feet²)=14.142 feet≈14.1 feet.
solution: side of square=14.1 feet.

Remark
You need to do some trig to get the final answer. There is no way around it. You can however, solve the first part with the Pythagorean Theorem.
Step One
Find AB
AB^2 = DB^2 + AD^2
AB^2 = 7.5^2 + 4.9^2
AB^2 = 56.25 + 24.01
AB^2 = 80.26
AB = sqrt(80.26)
AB = 8.9588
Step Two
Move to the triangle on your right. Find x
Tan(C)= opposite / adjacent
Tan(55.8) = AB/adjacent
Tan(55.8) = 8.9588/ x Multiply both sides by x
x * tan(55.8) = 8.9588 Divide by tan(55.8)
x = 8.9588/tan(55.8)
x = 6.09
Answer: A
The answer is 6 eggs per hen. You divide 72 by 12 to get 6. Hope it helps.
