The Sprinkler
An angle that turns through n one-degree angles is said to have an angle measure of n
degrees. A water sprinkler rotates one-degree at each interval, so if the sprinkler rotates
a total of 30 degrees, it has made 30 one-degree turns. Use this information to answer
the following questions.
1.
Joe is watering his lawn. If the sprinkler rotated 165 degrees, what is the
measure of the angle that the sprinkler has rotated? Create a model and write an
equation to show your answer.
2.
The measure of the angle that the sprinkler has rotated is 98 degrees. How many
one-degree turns has the sprinkler made?
3. The sprinkler rotated 45 degrees and pauses. It then rotates an additional 30
degrees. How many total degrees did the sprinkler rotate? Create a model and
write an equation to show your answer.
4.
It takes one half an hour for the sprinkler to rotate 180 degrees. If it continues
at this pace, how many degrees will it rotate in one hour? Create a model and write
an equation to show your answer.
