2/3x grades=2/3x×0.9°=3/5x°
π/75x radians=π/75x×180°/π=12/5x°
∴, (3/5+3/2+12/5)x°=180°
or, (6+15+24)/10x°=180°
or, (45/10)x°=180°
or, x°=180°×10/45
or, x°=40°
∴, 3/5x°=3/5×40°=24°
12/5x°=12/5×40°=96°
3/2x°=3/2×40°=60°
π/75x radians=π/75x×180°/π=12/5x°
∴, (3/5+3/2+12/5)x°=180°
or, (6+15+24)/10x°=180°
or, (45/10)x°=180°
or, x°=180°×10/45
or, x°=40°
∴, 3/5x°=3/5×40°=24°
12/5x°=12/5×40°=96°
3/2x°=3/2×40°=60°
