Question

find the value of x from the following figure​

Answer 1

Answer:

Step-by-step explanation:

=>∠1+70= 180 (linear pair)

=>∠1=180-70

=>∠1=110

now,

     =>∠2+60=180 (linear pair)

     =>∠2=180-60

      =>∠2= 120

now angle sum of pentagon is 540

                 =>30+x+x+120+110=540

                 =>           160+2x    =540

                 =>                   2x     =540-160

                  =>                     2x=    380

                 =>                        x   = 380/2

                =>                         x  =  190  

                  pls mark me as branliest

Answer 2

Answer:

=> <1+70=180 (linear pair)

=>1=180-70

=>1=110

now,

=>22+60=180 (linear pair)

=>22=180-60

=> 42=120

now angle sum of pentagon is 540

=>30+x+x+120+110=540

160+2x =540

2x

= 540-160

2x= 380

x=380/2

x=190
