Question

if sinx = 5/13 and x is in quadrant 1, then sin x /2 = .....
a. - sqrt(5/26)
b. sqrt(5/26)
c. - sqrt(1/26)
d. sqrt(1/26)

Answer 1

c.

Answer 2

bc?....

Answer 3

@sexy2handle the answer you just posted is considered cheating and can get you a warning for the moderators and a ban if you continue to distribute answers in that fashion after the warning please work with people through their problems do not just post answers even with work shown

Answer 4

Answer 5

well yes of course..and tbh @sexy2handle ...so many answers like that have been wrong i don't trust no explainations anyways....

Answer 6

which i why i asked "bc? or because?...

Answer 7

just so that I know what you are able to do in you math class are you able to use a calculator capable of reversing the "sin" operation

Answer 8

i have a ti 84 keypad on the inspire i own ..will that work? ..i think so?

Answer 9

reverse sin is ...-sin or 1/sin?

Answer 10

yes that calculator will work and how you get it solve for x when you have the ratio is by hitting the 2nd function key then hitting the "sin" key and finally entering the ratio, in this case 5/13

Answer 11

k
okay hsould i be in radians or degrees? in radians im at .39 about

Answer 12

i have to go

Answer 13

I think it should be in radians they are the typical unit of measurement where I live. Also remember they are asking you for sin(x/2) not x

Answer 14

alright...

Answer 15

oh btw..it wasn't c @sexy2handle .....why answer if you have no clue what you are talking about? ...you might just want to stick to asking questions. don't talk unless you know. im guessing thats why there was no reasoning either huh? ...way to fish for a medal
