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:
15 miles
Step-by-step explanation:
Let's say the dock is at the origin on a coordinate plane and each unit is 1 mile. If the boat travels 9 mile due north, that means that we move up from the origin (0, 0) 9 units to point A (0, 9). Now, this boat moves 12 miles due west, so we will go 12 units to the left of (0, 9) to point B (-12, 9). See the attached drawing (sorry for the crudeness).
Notice that this is a right triangle with legs of 9 and 12. That means the distance from the boat to the dock is just the hypotenuse, so use the Pythagorean Theorem: distance = 
Thus, the answer is 15 miles.
Hope this helps!

66597 g
divide by 1000
66.597 kg
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
Answer:
7 days
Step-by-step explanation:
2000-600 is 1400.
1400/200 is 7
2000=200x+600
x=7
