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°.
