Question

The angle 2x°and (3x-20)° are the linear pair angle than the value of x is

Answer 1

Step-by-step explanation:

if the both angle are linear pair so there some will be 180

so

2x+ 3x-20= 180

5x-20=180

5x=200

x=200/5

=40

Answer 2

Answer:

in linear pair sum of all angles is equal to 180°

so,here one angle is 2x°and another angle is (3x-20)° is given

now,2x + 3x- 20 =180(linear pair)

5x-20=180

5x = 180 + 20

5x = 200

x =200/5

x = 40

therefore,x= 40
