The given triangle is
To solve for PR, we have to use the sine function which is equivalent to the ratio between the opposite leg and the hypothenuse.

<h2>Hence, PR is 37.04 mm long, approximately.</h2>
Answer:

Step-by-step explanation:
Given that,
On a map, 9 cm represents 15 miles.
The distance between two cities is 15 cm. We need to find the distance in miles.
9 cm = 15 miles

So, 15 cm is equal to,

So, 15 cm on the map is equal to 25 miles.
