The angles of a triangle measure(x+10),(x+20)and(x+30)find the measure of the smallest angle measure

60
50
40
70

1 answer

The sum of the angles of a triangle is always 180 degrees.
Therefore, we have the equation: (x+10) + (x+20) + (x+30) = 180
Solving for x, we get:
3x + 60 = 180
3x = 120
x = 40

The angles are therefore: 50°, 60°, and 70°

The smallest angle measure is 50°.

Therefore, the answer is: 50.
