Question

find the value of x​

Answer 1

Step-by-step explanation:

as the sum of all the angles on a straight line is 180degree

so by adding all the angles in a equation form we can get the value of x

Hope it helps you

Answer 2

Answer.

(65-x)+20+(3x+17)+(x-12)=180- -eqs(1)

(As it is straight line this 180 degree)

Equating equation 1 we get

Or, 65+3x+20+17-12=180

Or, 90+3x=180

Or,3x=180-90

Or,3x=90

Or,x=90÷3=30

Now x is 30

For recheck

(65-30)+20+(3×30+17)+(30-12)=180

Done
