Question

three angles of a triangle are 2 X + 20 degree X + 30 degree and 2 x minus 10 degree find the angles​

Answer 1

Step-by-step explanation:

(x+10)+(2x-30)+x=180

4x-20=180

4x=180+20

4x=200

x=200/4

x=50

Answer 2

Step-by-step explanation:

2x + 20° + x + 30° + 2x – 10° = 180°

5x + 40° = 180°

5x = 180° – 40°

5x = 140°

x = 140°/5

x = 28°

So,

2x + 20° = 2*28° + 20 = 76°

x + 30° = 28° + 30° = 58°

2x – 10° = 2*28° – 10° = 46°
