Angle 1 and angle 2 are supplementary

1 = 124°
2 = (2x + 4)°

what is the value of x?

supplementary means equal to 180.

180 - 124 = 56.

56 = (2x+4)

2x = 52

x = 26

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
