Answer:
Smallest angle: 41°
Second angle: 57°
Third angle: 82°
Explanation:
Let's call the smallest angle as

"while a third angle is twice the smallest": third angle is

"One angle of a triangle measures 16∘ more than the smallest": 2nd angle is

We know sum of 3 angles in a triangle is 180 degrees, so we can set up the equation and solve for x:

So smallest angle is 41°
The 2nd angle is 16+41=57°
third angle is 2*41=82°
