Correct and 1st answer is brainliest

m<A = 40 deg

m<B = 60 deg

m<C = 80 deg

Step-by-step explanation:

2x + 3x + 4x = 180

9x = 180

x = 20

m<A = 2x = 2(20) = 40

m<B = 3x = 3(20) = 60

m<C = 4x = 4(20) = 80

m<A = 40 deg

m<B = 60 deg

m<C = 80 deg

A: 40°, B: 60°, C: 80°

Step-by-step explanation:

The sum of ratio units is 9. The sum of angles is 180°, so each ratio unit stands for 180°/9 = 20°.

A = 2×20° = 40°

B = 3×20° = 60°

C = 4×20° = 80°
