Answer:
Step-by-step explanation:
The figures are similar.
<u>Corresponding sides have same ratio:</u>
1)
- 18/24 = (x - 6)/39
- x - 6 = 39*3/4
- x - 6 = 29.25
- x = 35.25
2)
- 18/24 = y/27
- y = 27*3/4
- y = 20.25
Answer:
x = 49
Step-by-step explanation:
180-131=49
they are supplementary angles
Selling price = cost + 0.42*cost = 1.42*cost
cost = selling price/1.42
cost = $9182/1.42 ≈ $6466.20
