Let's first identify the angle for which we are looking. The symbol ∠COD refers to the angle found between the rays that start at O and pass through the points C and D.
Examining the protractor, we can see that the ray traveling through C passes through 30^(∘). Also, the ray traveling through D passes through 115^(∘). By the Protractor Postulate, the measure of ∠COD is the difference between 115^(∘) and 30.
m ∠COD: 115^(∘)-30^(∘)=85^(∘)
Now, we can classify the angle using its measure.
