<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

Hope it helps !!!</span>
Ok the formula for this is 2(lw +hw+hL)
2(30+35+42)=2(107)=214 square feet
Answer:
x = 4 - 1 = 3
Step-by-step explanation:
2(4 - y) + 3y = 9
8 - 2y + 3y =9
8 + y = 9
y = 1
Answer:
X = d/f - 1
Step-by-step explanation:
You would Isolate the variable by dividing each side by factors that don't contain the variable. Hope this helps
