a gas is compressed inside a compressor's cylinder. when the piston is at it's button dead center, the gas is initially at 10 ps
Andru [333]
Based on gas laws:

PV/T = Constant, P = Pressure, V = volume, T = Temperature (K)
Therefore,
P1V1/T1 = P2V2/T2

P1 = 10 psig
V1 = 10 in^3
T1 = 65°F = 291.483 K
P2 = ?
V2 = 1.5 in^3
T2 = 180°F = 355.372 K

Rearranging the equation,
P2 = P1V1T2/T1V2 = (10*10*355.372)/(291.483*1.5) = 81.279 psig

And right triangle sin (40 - x)° equals cos(3x)° degrees what is the value of x.
Drupady [299]

\qquad\qquad\huge\underline{{\sf Answer}}♨

Let's solve ~

\qquad \sf  \dashrightarrow \: \sin(40 - x)  =  \cos(3x)

\qquad \sf  \dashrightarrow \:  \cos\{90   -   (40 - x ) \}  =  \cos(3x)

\qquad \sf  \dashrightarrow \:90 - (40 - x) = 3x

\qquad \sf  \dashrightarrow \:90 - 40 + x = 3x

\qquad \sf  \dashrightarrow \:3x - x = 50

\qquad \sf  \dashrightarrow \:2x = 50

\qquad \sf  \dashrightarrow \:x = 25 \degree
