Answer:
2,3 and 4 are rational
Step-by-step explanation:
35 + 58 = 93, since all angles in a triangle are equal to 180 you can do 180 -93 to get the third angle, which is 87. Since x is in an exterior angle, 87+x =180. From there its simple. Subtract 87 on each side and you get x = 93.

Answer:
0.28 = 28% probability that a randomly selected driver will come to complete stop
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Recording of 75 drivers.
Of those, 21 came to a complete stop.
Then
21/75 = 0.28
0.28 = 28% probability that a randomly selected driver will come to complete stop
