Answer:
Part 1) and Part 2) in the procedure
Step-by-step explanation:
step 1
<em>Find the measures of angles</em>
we know that
The sum of the angles A, B and C must be equal to 360 degrees
Using a protractor
The measures of angles are
∠A=140°
∠B=100°
∠C=120°
step 2
Ordered the measures of the angles from least to greatest
1) ∠B=100°
2) ∠C=120°
3) ∠A=140°
The answer you are looking for is:
r = 3
