In a triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is 80 degrees more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180degrees to find the measure of each angle.

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual?
