The measure of arcPR and arcRPT are 83 and 208 degrees respectively
The measure of arc ST will be gotten using the expression below:
arcPS = arcPT + arcST
Given the following
arcST = arcPS - arcPT
arcST = 180 - 125
arcST = 55 degrees
Similarly, arcPR = 180 - arcRS
arcPR = 180 - 97
arcPR = 83 degrees
arcRPT = arcPR + arcPT
arcRPT = 83 + 125
arcRPT = 208 degrees
Hence the measure of arcPR and arcRPT are 83 and 208 degrees respectively

Answer:
11 music lessons.
Step-by-step explanation:
We know that membership costs $165 and members pay $25 per music lesson.
So, we can write the following expression:
The 165 represents the one-time membership fee and the 25m represents the cost for m music lessons.
We know that non-members pay no membership fee but their cost per lesson is $40. So:
Represents the cost for non-members for m music lessons.
We want to find how many music lessons would have to be taken for the cost to be the same for both members and non-members. So, we can set the expressions equal to each other:
And solve for m. Let's subtract 25m from both sides:
Now, divide both sides by 15:
So, at the 11th music lesson, members and non-members will pay the same.
Further Notes:
This means that if a person would only like to take 10 or less lessons, the non-membership is best because there is no initial fee.
However, if a person would like to take 12 or more lessons, than the membership is best because the membership has a lower cost per lesson than the non-membership.
And we're done!
- Natural numbers will Always be whole numbers.
Natural numbers are positive integers (whole numbers), so, they are always whole numbers.
- Integers will Sometimes be natural numbers.
Not all integers are natural numbers. Negative integers are not natural numbers while positive integers are natural numbers.
- Irrational numbers will Always be real numbers.
Real numbers consist of both irrational and rational numbers. So, all irrational numbers are real numbers.
- Rational numbers will Never be irrational numbers.
Rational numbers and irrational numbers are two different types of real numbers.
- Rational numbers will Sometimes be integers.
Not all rational numbers are integers. there are some rational numbers that are not integers while some rational numbers are integers.
