Use the information in the table. You are making a circle graph showing the total number of successful United States space launches. What is the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989?

153°
14.7°
86°
52.9°

Years -

52.9°

Step-by-step explanation:

step 1

we know that

The total number of successful United States space launches that happened in the years 1957-1995 is equal to

step 2

The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

step 3

The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

step 4

Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches  that happened in the years 1980-1989

we know that

In a circle, 360 degrees represent the 100%

so

using proportion

Find out the measure of the central angle by a percentage of 14.68%

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

1) letter c.

2) 4 square root of 9

hope this
