The answer would be A. angle-angle similarity. You know that angles D and E are congruent, and you also know that opposite interior angles are congruent (in this case ABE and CBD). The interior angles of a triangle must add up to 180 degrees, so the remaining angles A and C are also congruent. You don't know whether the sides of both triangles are congruent, so at best you can say they are similar.
Are all these the choices??
None of these can actually be the answer
The cost function, C(x) in terms of x, the number of refrigerators manufactured is written as C(x) = 1665 + 100x
The given parameters;
- total cost of manufacturing 160 refrigerators = $17665.
- total cost of manufacturing 182 refrigerators = $19865.
- total cost, C, is linearly related to the number of refrigerators, x
The linear equation is set up as follows;
C = b + ax
where;
- a is cost per refrigerator
First equation;
17665 = b + 160a -------(1)
Second equation;
19865 = b + 182a -----(2)
subtract equation 1 from equation 2 to solve for the value of a;
2200 = 22a

Solve for the value of b;
17665 = b + 160(100)
17665 = b + 16000
b = 17665 - 16000
b = 1665
<em>C(x) = b + ax</em>
<em>C(x) = 1665 + 100x</em>
<em />
Thus, the cost function, C(x) in terms of x, the number of refrigerators manufactured is written as C(x) = 1665 + 100x
