Question

in the given figure find the value of x​

Answer 1

Answer:

x= 50°

Step-by-step explanation:

(x+3)° + (x+20)° +(x+7)° = 180° [ linear pairs ]

3x + 30° = 180°

3x = 180° - 30°

x = 150°/3

x = 50°

Answer 2

Answer:

We know that sum of angle on a line is 180.

So by linear pair

angle1 +. angle2 + angle3 = 180

x+3+x+20+x+7=180

3x + 30 = 180

3x = 180-30

3x = 150

x = 150/3

x = 50
