Answer:
90 degrees
Step-by-step explanation:
Sum of the angles in a triangle = 180°
Opposite angles are equal
For two parallel lines and a transversal,
corresponding angles are equal, and
alternate angles are equal.
45+45=90.
180-90=90
Plus, you can see that the angle forms a perfect 90 degree angle.
Answer:
Step-by-step explanation:
Given that a company fixed costs are 400 dollars
and variable cost =
per unit and x the no of units produced
Selling price =
per unit
a) Break even units
At break even units selling price = variable cost

Break even units = 76
b) Revenue = Sales - total costs
= 
Use derivative test to get max revenue
R'(x) = 
R"(X) <0
So maximum when I derivative =0 or when

x=38
c) price when x =38 is
