A drawer contains 60 pairs of socks. Each pair is one of four colors. What is the minimum number of socks that must be drawn, at random, from the drawer to ensure that a pair of matching-color socks is selected?

Answer is 30

Step-by-step explanation:

Total no. Of pairs = 60

No. Of four colours = 60/4 = 15

To ensure matching pair drawn at random, minimum no. Of socks drawn should be 15x2 = 30

you can't solve x because it is 2 linear equation and you only have one equation

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
