<u>Given</u>:
The diameter of the circle P is 30 cm.
The radius of the circle P is 15 cm.
The measure of ∠RPS is 125°
We need to determine the arc length of QR.
<u>Measure of ∠QPR:</u>
The angles QPR and RPS are linear pairs.
Thus, we have;

Substituting the values, we have;


Thus, the measure of ∠QPR is 55°
<u>Arc length of QR:</u>
The arc length of QR can be determined using the formula,

Substituting
and r =15, we get;



Thus, the arc length of QR is 14.4 cm.
Hence, Option d is the correct answer.

Step-by-step explanation:



It’s “C” I got it right when I had this question before
Answer:
We should only choose a one-sided alternative if we have some reason to expect a specific directional outcome before looking at the sample results
Step-by-step explanation:
Wrong procedure applied by my friend, he use one sided hypothesis instead of two sided.
