1. The two triangles are similar because the two pairs of angles are equal, therefore the third angles of both triangles must also be equal.
We can call this the AAA similarity criterion
2. To find QR, we must use ratios between 2 known similar sides of both triangles,
So, QR =1.02
Answer:
The percentage change from July to November is 67.27 %
Step-by-step explanation:
Given as :
The number of tourists at the beach per weekend in the month of July = = 55,000
The number of tourists at the beach per weekend in the month of November = = 18,000
Let the percentage change from July to November = A %
Or, % decrease change = × 100
So , A % = - \textrm
}{\textrm
}[/tex] × 100
or, A % = × 100
Or, A % = × 100
Or, A = 67.27 %
So percentage change between two months = 67.27 %
Hence The percentage change from July to November is 67.27 % Answer
