The measures of the angles in a triangle add up to 180 degrees. So, we can set up the equation:
(x+10) + (x+20) + (x+30) = 180
Simplifying, we get:
3x + 60 = 180
Subtracting 60 from both sides, we have:
3x = 120
Dividing both sides by 3, we find:
x = 40
So, the smallest angle is (x+10) = 40°+10° = 50°.
Therefore, the answer is 50°.
