Triangle ABC is isosceles.
Angle ABC = 32º and AB = AC.
Find angle BAC.
Angle BAC =

angle BAC = 116

Step-by-step explanation:

since the triangle is isosceles and AB and AC are congruent, that means angle ABC and angle ACB are the same by the isosceles triangle theorem. so you know angle ABC and angle ACB are 32 and all angles in a triangle equal to 180. so you find angle BAC subtracting both of the 32 angles from 180 and you should get 116

she will most likely have 33  

step-by-step explanation:

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.
