19 POINTS AND BRAINLIEST IF YOU ARE THE FIRST ONE TO ANSWER

Caroline drew two triangles and used them to construct a rhombus with two acute angles and two obtuse angles. Which could be one of the triangles she used?
There is only one answer btw...

The first triangle

the angles follow a principle that may allow for obtuse angles

Step-by-step explanation:

the probability is 0

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.
