Question

find the value of x
​

Answer 1

Answer:

we know angle on straight line is 180 degree

so

x+20+x+10+x=180

3x+30=180

3x=150

x=50

Answer 2

Answer:x = 50 degrees

Step-by-step explanation:
so
3x + 10 + 20 =180

3x = 180 - (10 + 20)

3x = 180 - 30
3x = 150
x= 150 divided by 3
x=50 degrees
