The angles of a triangle measure (x + 10)°, (x + 20) °, and (x + 30) °. Find the measure of the smallest angle. (1 point)
0 50°
O 40°
O 60°
70°
The sum of the angles in a triangle is always 180°.
So, we have the equation: (x + 10) + (x + 20) + (x + 30) = 180
Solving for x:
3x + 60 = 180
3x = 120
x = 40
Now, we substitute x back into the expressions for the angles:
Smallest angle = (x + 10) = 40 + 10 = 50°
Therefore, the measure of the smallest angle is 50°.
The answer is 50°.
