Answer:
Angle A = 40
Angle B = 60
Angle C = 80
Step-by-step explanation:
The three angles of a triangle are in the ratio
2:3:4
Multiply by x
2x:3x:4x
The sum of the angles is 180 degrees
2x+3x+4x = 180
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
The value of x is 20
A B C
2*20:3*20:4*20
40 60 80
Angle A = 40
Angle B = 60
Angle C = 80

Step-by-step explanation:
But! A way you could solve this is to look at the opposite angle of 1 and see what the number is. The number opposite of 1 is always equal to 1. You could also see if there is a number next to 1. The number next to 1 +1= 180 degrees. Good luck!
