Step-by-step explanation:
It isn't proportional because 3/4 is proportional to 9/16 not 9/15.
Answer:

Explanation:
Here, we want to get the value of x and y
From the given image, the angle y and 116 lie on a straight line
The sum of the angles on a straight line is 180 degrees
Thus:

The sum of the internal angles of a polygon can be calculated by the formula:

where n is the number of sides the polygon has
In the case of the given question, n is 4
Substituting the value of n, we have it that:

To get the value of x:
Answer:
63/24
Step-by-step explanation:
First you change the whole 2 to have a fraction of 48/24.
Next you have change 5/8 so its denominator has a 24. So you multiple the 8 by 3 to get 5/24. But then you have to multiply the 5 by 3 also so it is still the same fraction just bigger and you get 15/24. Now add the 15/24 with 48/24 to get 63/24.
Hope this helps!
