Answer:
- W = 55°
- X = 125°
- Y = 110°
- Z = 70°
Step-by-step explanation:
Corresponding angles in similar figures are congruent. Corresponding angles are listed in the same order in the similarity statement.
∠A = ∠W = 55°
∠B = ∠X = 125°
∠C = ∠Y = 110°
∠D = ∠Z = 70°

Step-by-step explanation:
Answer:
p = -0.05m + 22
Step-by-step explanation:
As given in question,
The relation between the price and demand can be given by,
where is p is price and x is demand.
Since in order to sell 300 cards the price has to be fix at $7.
So,
7 = 300m+b <u> </u> (1)
And for every additional card they need to drop the price by $0.05.
So,
7-0.05 = 301m+b
=>6.95 = 301m + b<u> </u> (2)
Subtracting equation (1) from equation (2), we will have
6.95 - 7 = 301m - 300m
=>m = -0.05
By putting the value of m in equation (1), we get
7 = 300.(-0.05)+b
=> b = 22
So, the linear equation that show the relation between price and demand is given by
p = -0.05m + 22
