In a triangle, the measures of the three angles are x, x + 12 , and x-9. What is the measure of each angle?
2 answers:
Answer:
x+(x+12)+(x-9)=180
3x+12-9=180
3x=180-3
3x=177
x=177/3
x=59
Each angle is 59°, 71° and 500°
X + x + 12 + x - 9 = 180
3x = 180 - 12 + 9
3x = 168 + 9
3x = 177
x = 59 degrees
Angle 1 = 59 degrees
Angle 2 = 59 + 12 = 71 degrees
Angle 3 = 59 - 9 = 50 degrees
