Answer 5

never mind, if no one is gonna be helpful, i might as well just guess.

Answer 6

i got an idea :)

Answer 7

each "kite" shape has the property that the opposite angles add up to 180

Answer 8

and the given angles in the diagram are half the outside point

Answer 9

all the inner angles add up to 360, since they are central angles to a circle

180-2a + 180-2b + 180 - 2c = 360

-2a -2b + 180 - 2c = 0

-a -b + 90 - c = 0

-a -b + 90 = c

using the given angles as a and b

c = 90 - 32 - 34
