Answer:
(a)=40 (b)=60
Step-by-step explanation:
(a)=
So first 70 +70 = 140 then 180-140 = 40
(b)
So first 180/3 = 60 all angles =60
a=40 b=60
A explanation
70 + 70 = 140
180-140 = 40
B explanation
180/3= 60
all angles = 60
A explanation
70 + 70 = 140
180-140 = 40
B explanation
180/3= 60
all angles = 60
