What is the sum of the measures of the interior angles of a regular polygon if each angle measures 72

540 degrees.

Step-by-step explanation:

I assume that 72 degrees is the measure of  an exterior angle. This is the case in a pentagon because 360 / 72 = 5.

So each interior angle measures  180 - 72 = 108 degrees.

The sum of the interior angles = 5 * 108 = 540 degrees.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
