Step-by-step explanation:
Let the angle be x
then it is of ratio 2x : 3x : 4x
We know that sum of all angles of a triangle = 180
2x + 3x + 4x = 180
9x = 180
x = 180/90
x = 20
Therefore the angles are
2x = 2*20 = 40º
3x = 3*20 = 60º
4x = 4*20 = 80º
Answer:
40°,60°,80°
Step-by-step explanation:
2X+3X+4X=9X
180°÷9X=0
X180/9
X=20
2X=2×20=40°
3X=3×20=60°
4X=4×20=80°
