Answer:
C. m<XYA > m<ZYA.
Step-by-step explanation:
Since XY = YZ, as indicated in the information given, the angles opposite XY and YZ would also be of equal measure of degrees.
Thus, XA = 5. The angle opposite XA is m<XYA.
ZA = 3. The angle opposite ZA is m<ZYA.
Since XA > ZA, therefore,
m<XYA > m<ZYA.
Using thereoms/postulates, we know that the 60° angle and the (5z - 85)° angle are congruent
so to first find z..



now that we know z, we can find x
simply replace the z in (5z - 85) with 29
and add the entire angle to x to equal 180
(supplementary angles)




If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

For example:
1/2 + 1/3
We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.
The LCM of 2 and 3 is 6. So, our LCD 6.
We need to make this our new denominator...
Change the 1/2:
1 x 3 over 2 x 3 = 3/6
Change the 1/3:
1/2 + 1/3 = 3/6 + 2/6
Now we can do it!
(3+2)/6 = 5/6
Given:
Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.
To find:
The ratio of jerome's share to kevin's share to seth's share.
Solution:
Jerome ate 1/2 of the sandwich. So,
Jerome's share = 
Kevin ate 1/3 of the sandwich. So,
Kevin's share = 
Seth ate the rest. So,
Seth's share = 
= 
= 
The ratio of jerome's share to kevin's share to seth's share is:

To simplify the ratio multiply the ratio by 6.


Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.
