<span> tan(x)/ cos(x)-sec(x)
tanx/(cosx-1/cosx)
tanx/cos^2x-1)--------------------1-sin^2x=cos^2x
-tanx/sin^2x
-(sinx/cosx)/sin^2x
-1/sinxcosx
multiply 2/2
-2/2sinxcosx-------------sin2x=2sincosx
-2/sin2x------------------1/sinx=cosecx

Perimeter is all four sides added together, therefore....
38+38= 76
8dm= 80cm
80cm*2=160 cm
76+160= 236<span />
I think the answer is 360
This is what i got in the caculator 6400 if not im so so sory
