Answer:
let the angle A=x
angles B= 3x-2°
angle c = angles B+9°=. 3x-2+9°
3x+7°
angle A + angle B + angle C= 180°
x+(3x-2)+(3x+7)= 180°
x+3x-2+3x+7=180°
7x+5°=180°
7x=180°-5°
7x=175°
x=175°/7
x=25°
angles A= 25°
angle B= 3x-2°
=3(25°)-2
=75°-2°=73°
angle B =73°
angle C= Angle B+9°
73°+9°
angles C =82°
25°,73°,82°
