Answer:
a=20°
b=70°
c = 20°
d = 70°
e= 110°
Step-by-step explanation:
90° = a + 70
20° = a
90° =a + b
20° = a
90° = 20° + b
70° = b
c + b + a + 70° = 180°
c + 20° + 70° +70° = 180°
c = 20°
a + b + c + d = 180°
70° + 20° + 20° + d = 180 °
d = 70°
d + e = 180
70° + e = 180°
e= 110°
Hope this helps ^-^
