since there are 180 degrees in a triangle so :
65+72+y=180 add like terms
137 + y=180 now subtract 137
y= 180-137
y=43 degrees
The variable which is a categorical variable among the answer choices as in the task content is; Population of the state.
<h3>What is the categorical variable among the answer choices?</h3>
Categorical variables represent types of data which may be divided into groups. Instances of categorical variables include but are not limited to race, sex, age group, and gender.
It therefore follows from the traditional definition of categorical variables that the answer choice which represents a categorical variable is; Population of the state.

Answer:
Step-by-step explanation:
Using the Z theorem, the upper angle on the right = 60 degrees.
The angle which includes 3x is 120 because this is a parallelogram and consecutive angles must add to 180. So 180 - 60 = 120
The angle above the 3x is 120 - 3x
120 - 3x + 90 + 2x = 180 These angles make a straight line line. Combine.
210 - x = 180 Subtract 210 from both sides.
- x = 180 - 210 Combine
-x = - 30 Multiply both sides by - 1
x = 30
the answer is 45
because I know 15+15=30 and 30+15=45
so 45-15=30
hope it helps :)
