Adjacent angles ABD and DBC. The measure of angle ABD is 20 degrees. If m∠ABC = 80°, what is m∠DBC? Justify your reasoning. Using the Angle Addition Postulate, 20 + m∠DBC = 80. So, m∠DBC = 60° using the subtraction property of equality. Using the Angle Addition Postulate, 20 + 80 = m∠DBC. So, m∠DBC = 100° using the addition property of equality. Using the addition property of equality, 20 + 80 = 100, so m∠DBC = 100°. Using the subtraction property of equality, 80 − 20 = 60, so m∠DBC = 60

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.

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
