Answer 10

anyone?

Answer 11

welsh?

Answer 12

one way would be to find the middle angles by applying the cosine rule to the left side triangle . Then apply it to the one on the right to find length of FG.

Answer 13

Indeed

Answer 14

IGNORE BELOW PICTURE

Answer 15

why? lol

Answer 16

because it's for another problem ;)

Answer 17

anyways, continue

Answer 18

oh ok!

Answer 19

Cos x = 82^2 + 92^2 - 47^2 / (2.82.92)
x = 30.66 degrees
then
FG^2 = 82.8^2 + 73.8^2 - 2* 82.8*73.8 cos 30.66
= 42.30

Answer 20

FG = 42.30

Answer 21

x=?

Answer 22

ooh my bad

Answer 23

that is for the other one.

Answer 24

good job mate!

Answer 25

the other one is 2 similar pentagons
