JIG is clockwise around the figure, as is DEF, so there is no reflection involved. The midpoint between any two corresponding vertices is (1, 4), so that is the center of rotation. Figure DEF is "upside down" from JIG, so rotation is 180°.

The 1st selection is appropriate.

Use the information in the table. You are making a circle graph showing the total number of successful United States space launc

Answer:

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

$15+470+258+153+146=1,042$

step 2

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

$153$

step 3

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

$\frac{153}{1,042}(100)=14.68\%$

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%

using proportion

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

$\frac{360^o}{100\%}=\frac{x}{14.68\%}\\\\x=360^o(14.68\%)/100\%\\\\x= 52.9^o$
