Answer:
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Let's add the three angles we are given and see what the sum is.
- The three angles are 127, 38, and 15
Add them together.
- 127+38+15=180
- 3 angles = 180 degrees
The three angles equal 180 degrees, therefore they can create a triangle.
Answer:
10/3
Step-by-step explanation:
31/8= 3.8
10/3= 3.3
A number is less than 4 units from 0
-4<x<4
If the angle is mesure in RADIANS then the arc is given by r. So first convert 81 degrees to radians, then multiply by r which is 10 x 81=810
