Answer 1

Answer:

4√30 or -4√30

Step-by-step explanation:

[.] ⇒ $x$

$\frac{5}{3} \times \frac{4}{x} =\frac{x}{72}$

$\frac{20}{3x} =\frac{x}{72}$

$x^2=20\times 24=2^2\times 5\times 2^3\times 3=2^4\times30$

$x=\pm4\sqrt{30}$

Answer 2

Answer:

4√30

Step-by-step explanation:

Let the empty space be X

so,15/9*4/X = X/72

or,15/9*4*72 = x^2

or, 480 = x^2

or, X = √480

= 4√30
