What is the supplement of a 136 degree angle?

a 44 degree angle

Step-by-step explanation:

Supplementary angles are a pair of angles that for 180 degrees. The supplement of a 136 degree angle would be a 44 degree angle because 136 + 44 = 180.

136 + x = 180

136 - 136 + x = 180 - 136

x = 44

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
