ANSWER:
Angles 2 and 4 are vertical angles, which means they have the same angle measure because they are opposite of each other. So angles 2 and 4 are both 114 so that makes 228. All of the angles have to make 360, so 360 - 228 = 132. Then, 132/2 because there are two angles. That makes 66. And angles 1 and 3 are also vertical angles so they are also the same
The answer is 132
to be sure that 2 of them will be blue i have to select 7+2=9 balls
7+8=15 balls in the urn
P=9/15
to be sure that 4 of them will be yellow i have to select 8+4=12 balls
P=12/15
144
1,728 divided by 12 is 144
#1) Arrange the numbers from least to greatest.
#2) If there is a odd amount of numbers the middle number is your answer.
but if there is a even amount of numbers, take those two middle numbers, add them, then divide them by two. Then you got your answer.
