Question

please give me answer step by step ​

Answer 1

Answer:

500

Step-by-step explanation:

we know sum of angles in Pentagon is 540

so, 60+70+90+50+c= 540

c= 270

consider a line having angles a and 60

we know angle of line is 180

a+60=180

a=120

similarly,b=110

a+b+c=270+110+120

=500
