Hi anyone can help me ??

Step-by-step 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

the radius is multiplied by √6.

step-by-step explanation:

if a circle has a radius of 10.9 cm and the area is multiplied by 6, the radius is multiplied by √6.
