x is 14.3

$\frac{x}{ \sin(a) } = \frac{y}{ \sin(b) }$

the right angle is 90 degrees, so sin(a) is 90

$\frac{x}{ \sin(90) } = \frac{9}{ \sin(39) }$

multiply sin(90) on both sides to give:

$x = \frac{9}{ \sin(39) } \times \sin(90)$

x is 14.3

Which of the following choices are equivalent to the expression below? check all that apply

Naddika [18.5K]

The choices are equivalent to the expression correct choices are A, C, and D.

The given expression is

x^3 /5

<h3>What is the expression?</h3>

The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.

<h3>What is the power rule?</h3>

$a^{\frac{m}{n} =\sqrt[n]{a^m}$

Therefore the above power rule implies that,

$x^{(\frac{3}{5}) }=\sqrt[5]{x^3}$

Also, we have the power rule

$(a^m)}^n=a^{mn}$

$x^{\frac{3}5} =(x^3)^{\frac{1}{5}$

or it can be written as

$x^{\frac{3}{5} =(\sqrt[5]{x})^3$

The correct choices are A, C, D.
