Answer 14

sorry... how are you getting 2 decimal places...?

Answer 15

idek i dont understand this can u show what to do from the start plz

Answer 16

LG is the diameter... so everything on the left half is 180 degrees... yeah?

Answer 17

so looking at the left half only:
GH is 74.8
and HL is 4x

Answer 18

so GH + HL is 180 degrees... with me?

Answer 19

@Addicto_ do you follow so far?

Answer 20

yes im listening

Answer 21

ok, cools
so GH + HL = 180 degrees
74.8 + 4x = 180
now please solve for x @Addicto_

Answer 22

4x = 105.2
x = 26.3

Answer 23

perfect
now we need to find AU
AU = 2x
so AU = ?

Answer 24

wait how am i supposed to find AU

Answer 25

you know the value of x...
the arc AU is 2 time the value of x

Answer 26

*times

Answer 27

so 26.3 * 2 ?

Answer 28

yep

Answer 29

52.6

Answer 30

perfect

Answer 31

also understand now where you were getting 2 decimal places from... whoever wrote the question did it ...wrong... sorry for doubting you @MARC_ ... looks like they rounded the value of arc GH

Answer 32

ok thanks so much
