Answer 6

agree with Dan
GN = AN
HN bisector so angle HNA = 45

Answer 7

The its 225?

Answer 8

To measure angles start at C go anticlockwise CNH = (90 + 45) = 135 CNE = -90
the arc is the ratio of measure of the angle with circumference of the circle. the length is always positive. 135 + 90 = 225
arc HBE = HBC + CDE

HABCD is a straight line 180 and DNE = HNA = 45 so DE = 45
HABCDE = 180 + 45 = 225

angle/360 = length of arc/2*pi*r

different views of the same diagram same principle
