Can you say the total cost? There's not enough to go by to answer this.
Answer:
Two solutions (-4,-7) and (4,7)
Step-by-step explanation:
x = y + 3
x*y = 28
(y+3)*y=28
y^2+3y-28=0
(y+7)(y-4)=0
y=-7, y=4
x=-4, x=7

Since all the sides would be scaled together, all the angles would still be similar.
The answer should be:
∠A ≅ ∠A'
∠B ~ ∠B'
81 and above
They have to be 81 and above
93+69+89+97=348
348/4=87 (average)
87=81=168
168/2= 84 (average)
