Answer 1

let cos theta = x \[\huge\rm -1 - \frac{x}{2}= \frac{-4-\sqrt{3}}{4}\]
now can you slve for x ??

Answer 2

solve **

Answer 3

x=(2+√3)/2

Answer 4

hmm that's not correct how did you get 2 at the numerator ?? :=))

Answer 5

multiple 2 from the x to the 4 being divided?

Answer 6

to get rid of the fraction you would multiply both sides by 4
but first get the common denominator at left side

Answer 7

give me a minute
sorry

Answer 8

make sense ?
or maybe show ur work so i can find out the mistakes :=))

Answer 9

sure take ur time :=))

Answer 10

you would move the -1 to the right ? before finding the cmd?

Answer 11

the easy way is to get the common denominator at left side first \[\frac{ -1 }{ 1 }- \frac{x}{2}\]

Answer 12

-4/4?

Answer 13

then it would be move to the right side?

Answer 14

hmm no \[\huge\rm \color{reD}{-1 - \frac{x}{2}}= \frac{-4-\sqrt{3}}{4}\]
first solve left side
find common denominator

Answer 15

btw how did you get -4/4 ?

Answer 16

-1-2x/4=...

Answer 17

hmm i have not idea how did you get 4 ?

Answer 18

the common demoninator is 4?

Answer 19

lets work on left side \[\frac{ -1 }{ 1 }- \frac{x}{2}\]
both denominator aren't the same so we should multiply them
ignore right side for a sec :=))

Answer 20

hmm not left hand side:common denominator isn't 4

Answer 21

oh then it would be (-2/2)-x/2

Answer 22

?

Answer 23

right \[\huge\rm \frac{-2-x}{2}= \frac{-4-\sqrt{3}}{4}\] now multiply both sides by 4 :=))

Answer 24

brb sorry gimme few mints :=))

Answer 25

its fine :)

Answer 26

-4-x=-4−√3

Answer 27

x=√3

Answer 28

-2 and -x both should be multiply by 2
