Answer 1

Yes, 3 triangles have 180 degrees because the interior angles of a triangle must add to 180 degrees.

Answer 2

`\boxed {\tt Yes}`

`\boxed {\tt The \ 3 \ angles \ add \ to \ 180 \ degrees}`

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.
