Given the figure of a cyclic quadrilateral
The sum of the opposite angles = 180
so, we can write the following equations:

we will find (x) from equation (1):
x = 180 - 100 = 80
We will find (y) from equation (2):
2y = 180 - 102
2y = 78
y=78/2 = 39
So, the answer will be:
x = 80
y = 39

Answer:
-437
Step-by-step explanation:
x=3,y=13,z=5
12x-3y4x-z
12(3)-3(13)(4)(3)-5
36-468-5
-437
Answer is choice DThis is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.
To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)
Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.
