The angles of a triangle add up to 180 degrees.
Let's represent the extended ratio as 3x:5x:7x.
So, the sum of the angles is 3x + 5x + 7x = 15x.
We know that 15x = 180 (the sum of the angles of a triangle is 180 degrees), so x = 12.
Therefore, the angles are 36 degrees, 60 degrees, and 84 degrees.
The smallest angle is 36 degrees, so the answer is B) 36°.
