The original number is 438.48. Hope this helps!
Tanx sinx (cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x 1/sinx- sinx)
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(1/cosx)((cos^²x - sin²x)]
=(1/cosx)(2cos²x====> = 2 cos x]
Answer: 12/13 or -12/13
Step-by-step explanation: x^2=144/169
Sqrt(x^2)=sqrt(144/169)
take the square root of the top and bottom
x=12/13 or -12/13
