Select all the conditions for which it is possible to construct a triangle. a triangle with angle measures 60, 80,and 80. A triangle with side lengths of 4cm, 5cm, and 6cm. A triangle with side lengths of 4cm, 5cm, and 15cm. A triangle with side lengths of 4cm, 5cm, and a 50 degree angle. A triangle with angle measures 30, 60, and a 3cm side length. PlZ HELP THE QUARTERS ALMOST OVER AND THIS IS MY LAST TEST FOR MATH!!

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

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.
