Answer:

  239

Step-by-step explanation:

Write the equation. Fill in the given values, and solve for the unknown,

  z = k√x

  717 = k√9

  k = 717/3 = 239

The constant of proportionality is 239.

Answer:

z =  \sqrt{x}  \\ invite \: constant \\ z = k \sqrt{x}  \\ 717 = k \sqrt{9}  \\  \frac{717}{ \sqrt{9} }  =  \frac{k \sqrt{9} }{ \sqrt{9} }  \\ k =  \frac{717}{3}  \\ k = 239

Answer:

x = 9º

∠B = 40º

Step-by-step explanation:

5x-5º = 3x+13º

<em>[add 5 to both sides]</em>

5x = 3x+18º

<em>[subtract 3x from both sides]</em>

2x = 18º

<em>[divide each side by 2]</em>

x = 9º

3x+13º = 3(9º)+13º=27º+13º = 40º
