Which expression can be used to find the value of x?

a) 23(sin55°)(sin85°)

b) 23(sin85°)sin55°

c) 23(sin55°)sin85°

d) (sin55°)(sin85°)23

Step-by-step explanation:

It looks like you are using the sine law.

23/Sin(85) = x /  sin(55)     Cross multiply

23*sin(55) = x * sin(85)

23*sin(55)/sin(85) = x

None of these answers look correct. One thing you could try is

sin(85) = cos(90 - 85)

sin(85) = cos(5)

That would give you

x = sin(55)*cos(5)

If that is not among  your choices you have no answer.
