Question

find the value of x:-​

Answer 1

Answer:

angle AED= 180-90=90

angle EDC=180-60=120

angle ABC=180-40=140

we know, sum of interior angle of a pentagon = 540

angles AED+EDC+BCD+EAB+ABC=540

BCD+90+120+90+140=540

angle BCD=540-440=100

therefore x=180-angle BCD

                  =180-100

                   =80   ans....
