Find the values of x and y. y 45

Mila [183]

Answer:

x = $\sqrt{2}$

y = 2

Step-by-step explanation:

By applying tangent rule in the given triangle,

tan(45°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

1 = $\frac{\sqrt{2}}{x}$

x = √2

By applying sine rule in the given triangle,

sin(45°) = $\frac{\text{Opposite side}}{\text{Hyotenuse}}$

$\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{y}$

y = $(\sqrt{2})^2$

y = 2

Write r=-8sec(theta) in rectangular form

Airida [17]

$r=-8\sec\theta=-\dfrac8{\cos\theta}\implies r\cos\theta=-8$

Converting from rectangular coordinates to polar coordinates involves setting $(x,y)=(r\cos\theta,r\sin\theta)$ . Since the left hand side matches $x$ perfectly, the equation's rectangular coordinate form is $x=-8$ .
