Each exterior angle of a regular polygon measures 30 degrees how many sides does the poly gon have a. 11 b. 12 c. 15 d. 10

B

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

If n is the number of sides, then divide sum by exterior angle

n = = 12 → B

159 text messages

Step-by-step explanation:

Given that:

Predicted average = 2042

Number of months = 6

Number of texts for each of last 5 months :

Let number of text that must be sent in the sixth month = x

Predicted Average = (sum of texts / Number of months)

2042 = (2800 + 2481 + 2105 + 1975 + 2732 + x) / 6

2042 = (12093 + x) / 6

Cross multiply :

6 * 2042 = 12093 + x

12252 = 12093 + x

x = 12252 - 12093

x = 159
