Can someone please help ?? Will mark Brianliest

34

Step-by-step explanation:

I hope you can read this. It is the only way I could think of putting it up for you.

The first diagram is the given situation.

The second diagram asks you to ignore the 98 degree angle and extend the line making up the 116 degree angle until it hits the parallel line on your right. You can then find the supplement to the vertically opposite angle because angles on the same side of the transversal and are interior angles are supplementary. You should get 64.

The third diagram finds the supplement to the 98 degree angle (and yes the 98 degree angle is back in the picture again).  You should get 82

You now have 2 known angles in a triangle. The third diagram finds y and <4 to be 34 That's your answer.

could you reply to this with the question so i can ?

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.
