Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
Answer:

Step-by-step explanation:
2p + 3r = q
2p + 3r - 3r = q - 3r [ subtract 3r from both sides ]
2p + 0 = q - 3r [ -3r + 3r = 0 ]
2p = q - 3r
[ divide by 2 on both sides ]
