Answer 1

The sum of the angles in a triangle is always 180°.

Therefore, we can set up the equation:

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

Combining like terms:

3x + 60 = 180
3x = 120
x = 40

Plugging x back into the expressions for the angles, we get:

Smallest angle = x + 10 = 40 + 10 = 50°

Therefore, the measure of the smallest angle is 50°.

Answer: 50°
