4. the distance from the center of a compact disc to the edge of the disc is 6 centimeters. what's the area of the compact disc?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
