40°
how do u know
We know that the sum of the angles in a triangle is always 180°.
So, we can set up the equation:
(x+10) + (x+20) + (x+30) = 180
3x + 60 = 180
3x = 120
x = 40
Thus, the measure of the smallest angle would be x + 10 = 40 + 10 = 50°.
So, we can set up the equation:
(x+10) + (x+20) + (x+30) = 180
3x + 60 = 180
3x = 120
x = 40
Thus, the measure of the smallest angle would be x + 10 = 40 + 10 = 50°.
