Thank youu!!! have a great day
I'm assuming you're comparing two triangles? If not, then this is probably wrong.
Triangle = 180 degrees
180 divided by 3 = 60 degrees
since ∠1 ≅ ∠2 ≅ ∠3, each angle equal 60 degrees
∠4 ≅ ∠5
m∠4 = m∠3 + 10
m∠3 + 10 = m∠5
we know that m∠3 is 60 degrees.
60 + 10 = 70, so m∠5 is 70 degrees
70 degrees is the answer.
From the information provided, A single-price monopolist earns a total profit of $80 when it produces and sells 20 units of its good. See the attached for more information.
<h3>How do we arrive at $80?</h3>
Total profit = revenue - cost
Revenue = price x number of units sold
Revenue at 20 units =
20 x9 = $180
Given that Total cost at 20 units is $100, thus,
Total Profit = 180 - 100
= $80.
