The measure of the smallest angle is x + 10°.

To determine the value of x, we can set up an equation:

(x + 10) + (x + 20) + (x + 30) = 180

Combining like terms:

3x + 60 = 180

Subtracting 60 from both sides:

3x = 120

Dividing both sides by 3:

x = 40

Therefore, the measure of the smallest angle is 40°. Answer: 40°.
