to find X you need to add up the other two angles inside the triangle which are 36 and 63, that equals 99 and then subtract that number from 180, which equals 81.
To find Z you will follow the 180 rule and subtract 180 from what you got for X(81), this will equal 99
To find Y you will add what you got for Z(99) plus 13 and then subtract that number from 180, which will give you 68
So X=81, Y=99, and Y=68

Step-by-step explanation:
If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.
Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.
This applies with any combination.
This means that the probability of you getting two silvers in a row is 0.25.
Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.
Hope this helped!
Answer:
12
Step-by-step explanation:
You need the greatest common factor of 168 and 60.
168 = 2^3 * 3 * 7
60 = 2^2 * 3 * 5
For the GCF, you need common factors with the lower exponent.
Between 2^3 and 2^2, choose 2^2.
Then you have 3 as a common factor.
5 and seven are not common.
GCF = 2^2 * 3 = 12
