Question

answer should be 40° how?​

Answer 1

Answer:

No, answer should be 20°

Step-by-step explanation:

2X+6X+X=180 ( sum of all angle of triangle is 180)

9X=180

X=180÷9

X=20°

Answer 2

Answer:

x is 20°

Step-by-step explanation:

Sum of angle of triangle = 180°

2x° + 6x° + x° = 180°

9x° = 180°

x° = 180°/9

x° = 20°

It is 20° not 40°

x° = 20°

2x° = 2 x 20° = 40°

6x° = 6 x 20° = 120°
