Answer:
Explanation:
a) The name of the figure is a pentagon.
b) You need to find <HBA. Before you can do that, you need to get the interor angle of 43 and 104
EAF = 180 - 43
EAF = 137
HCD = 180 - 52 = 128
CDE = 180 - 104
CDE = 76
Now you can get <HBA = 540 - 76 - 137 - 90 - 128 = 540 - 431 = 109
x = 180 - 109 = 71
