Find the length of side x in simplest radical form with a rational denominator.
alekssr [168]

Answer:

x = \frac{2*\sqrt{3}}{3}

Step-by-step explanation:

Reference angle = 30°

Opposite side = x

Adjacent side = 2

Apply the tan trigonometric function, thus:

tan (30) = \frac{opp}{adj}

tan (30) = \frac{x}{2}

2 * tan (30) = x

2 * \frac{1}{sqrt{3}} = x (tan 30 = 1/√3)

\frac{2}{sqrt{3}} = x

Rationalize

\frac{2* \sqrt{3}}{sqrt{3} * \sqrt{3}} = x

\frac{2*\sqrt{3}}{3} = x

-3x + y = 22<br> -12x – 10y=-10
dimaraw [331]

Answer:

<h3>               x = -5,  y = 7</h3>

Step-by-step explanation:

-3x + y = 22     ⇒  y = 3x + 22

-12x - 10y = -10  and  y = 3x + 22

-12x - 10(3x + 22) = -10

-12x - 30x - 220 = -10

               +220       +220

 - 42x  = 210  

 ÷(-42)     ÷(-42)

    x = -5

y = 3(-5) + 22 = -15 + 22 = 7

The area of a rectangular patio is 384 square feet.
Usimov [2.4K]

the ratio of the length and width = 3:2

Step-by-step explanation:

let the length be =x

width be = \frac{2x}{3}

area of a rectangle = length X width

so, x X \frac{2x}{3} = 384

or, x^{2} X 2/3 = 384

or, x^{2} = (384 X 3)/2

= 576

or, x = 24 ( taking square root)

hence, length is 24

width is = 24 X (2/3)

=16

so the ratio of length and width = 24 : 16

= 3:2
