The image shows a pie chart representing extracurricular activities and their popularity among students, with the total number of students being 480. The chart gives angle measurements in degrees for each activity, as follows:

• ISC (Islamic Study Club) (angle not provided)
• Marawis: 140°
• Teater: 70°
• Futsal: angle not provided

The problem is asking to calculate how many students participate in ISC, with multiple-choice options (a: 40, b: 50, c: 60, d: 70, e: 80).

To solve this:

1. The total degrees in a circle is 360°, which represents the 480 students.
2. We need to calculate the degree for ISC and then determine the number of students corresponding to that degree.

I'll calculate it for you.

Let me start by determining the angle for ISC.The angle for ISC (Islamic Study Club) is 150°.

Now, let's calculate the number of students who participate in ISC. Since 360° represents 480 students, we can use a proportion to find the number of students corresponding to 150°.

I'll calculate that next.The number of students who participate in ISC (Islamic Study Club) is 200.

It appears that none of the provided options match this value, so there may be an issue with the answer choices listed or the problem setup.
