Answer:
The smallest angle is 25°
Step-by-step explanation:
A triangle has 180 degrees.
(2x - 11) + (3x + 15) + (4x + 14) = 180
Simplify:
9x + 18 = 180
Subtract 18 from both sides:
9x = 162
Divide both sides by 9:
x = 18
Now you can calculate the measures of the angles:
2(18) - 11 = 25°
3(18) + 15 = 69°
4(18) + 14 = 86°
The smallest angle is 25°
