Considering that the data is only noted and not changed, this is an example of an observational study.
<h3>What are observational and experimental studies?</h3>
- Experimental study: In an experimental study, there is an intervention in a sample, and it's effect is studied.
- Observational study: In an observational study, the sample is just analyzed, without any intervention.
In this problem, the data, which is the number of miles traveled, is only analyzed, no interventions are made, hence this is an example of an observational study.

Answer:
Type of angle - Obtuse
Key information - 180° - 82° = 98° (missing angle)
Equation - 
Step-by-step explanation:
Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.
then use the statement to solve for y and make it equal to 98°
= -12 subtract 12 from both sides
= 86 Now solve for y by dividing 86 ÷ 5
y = 17.2
