Someone please help me. How do you find y

Schach [20]

X and Y are vertical angles, which mean they are the same.

The 3 inside angles need to equal 180 degrees, so solve for X:

X = 180 - 35 - 65 = 80 degrees.

Y = 80 degrees.

Find an equation of variation for the given situation: y varies jointly as x and the square of z and inversely as w, and y= 27/

Answer:

$y=\dfrac{6xz^2}{w}$

Step-by-step explanation:

When y varies jointly as x and z, the equation is written ...

y = k·x·z

Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...

y = k·x·z²/w

We want to find the value of k for the given values of the variables. So, we can solve for k to get ...

$k=\dfrac{wy}{xz^2}=\dfrac{8\cdot\dfrac{27}{2}}{2\cdot3^2}=\dfrac{4\cdot27}{2\cdot9}=2\cdot3=6$

Then the equation of variation is ...

$\boxed{y=\dfrac{6xz^2}{w}}\qquad\textbf{matches B}$
