Jada is making a circle graph of her college tuition and fees. She spends 10% of her expenses on board. Since a circle has 360º, lada
knows that the central angle for that section of the graph is 36° She thinks she can use what she knows about angle relationships to
help her figure out the number of degrees for the central angle for the section of the graph that represents her room expenses. Which
equation could be used to help her solve this problem?

Answer:

72 degrees

Step-by-step explanation:

i did it and it was 72°

The required equation will be [tex]\frac{expenses }{100}[/tex]×360.

Definition of central angle

Central angle is the angle subtended by an arc of a circle at the center of a circle.

According to the question

we have,

10% fee = 36 degrees

⇒ 100% = 36×10 = 360 degrees

⇒ full expenses is shown by 360 degrees.

and, x is the expenses of her room.

therefore,

angle measure for room expenses =  [tex]\frac{room expenses percent}{100}[/tex]  × 360

angle measure for room expenses = [tex]\frac{15}{100}[/tex] ×360

angle measure for room expenses = 54 degrees.

hence, the equation for the angle measure is  [tex]\frac{expenses}{100}[/tex]×360.
