Answer:
We can call the angles 2x, 3x, and 4x. Since the sum of angles in a triangle is 180 degrees we can write:
2x + 3x + 4x = 180
9x = 180
x = 20 so the angles are 40°, 60°, and 80°.
Answer:
40, 60 and 80 degrees.
Step-by-step explanation:
If the angles are proportional to 2, 3, 4, then the angle measures are 2x, 3x and 4x
2x+3x+4x=9x
Angles in a triangle add to 180 degrees, so x=20
2x=40
3x=60
4x=80
Thus, the angles are 40, 60 and 80 degrees.
