Question

А a 80° E B 150° · Find a + b + c + d + e in the figure. e b d 70° C D C​

Answer 1

Answer:

540 degrees

Step-by-step explanation:

a=180-80=100 degrees (linear pair)

b=180-150=30 degrees (linear pair)

c=180-90=90 degrees (linear pair)

d=180-70=110 degrees (linear pair)

angle EAD=540-(other 4 angles)

                 =540-390=150 degrees

e=180-150=30 degrees (linear pair)

a+b+c+d+e=100+30+90+110+150

                  =540
