If tan 145° = -143, what is tan -125°?

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

is there any other information given for this problem? this is not enough information.
