8 0

Answer:

<h2>23.6°</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • trigonometry i.g sin(x)=opp/hypo
  • PEMDAS
<h3>given:</h3>
  1. opp:6
  2. hypo:15
<h3>to find:</h3>
  • xyz angle

<h3>let's solve:</h3>

let \: xyz \: angle \: be \:  \alpha

according \: to \: the \: question

\sin( \alpha )  =  \frac{xy}{zy}

\sin( \alpha )  =  \frac{6}{15}

\alpha  = asin( \frac{6}{15} )

\alpha  =  {23.6}^{o}

therefore

<h3>xyz angle=23.6°</h3>

R = sec(θ) − 2cos(θ), where -π/2 &lt; θ &lt; π/2
Alex

Answer:

  y = (x/(1-x))√(1-x²)

Step-by-step explanation:

The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:

  x = r·cos(θ)

  y = r·sin(θ)

  x² +y² = r²

__

  r = sec(θ) -2cos(θ)

  r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)

  r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²

  (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations

  x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor

  y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

  \boxed{y=\dfrac{x\sqrt{1-x^2}}{1-x}}

__

The attached graph shows the equivalence of the polar and rectangular forms.
