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

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

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

What are the solutions of the following system? y=-2x^2 y=x-2

vovikov84 [41]

Answer:

x = 0.781 , y = -1.219

and

x = -1.281 , y = -3.281.

Step-by-step explanation:

Since both of the x terms are equal to y we can equate the x terms:-

-2x^2 = x - 2

2x^2 + x - 2 = 0

x = [-1 +/- √(1^2 - 4*2*-2) ] / 4

= ( - 1 +/- √(17)) / 4

= 0.781, -1.281.

When x = 0.781 y = 0.781 - 2 = -1.219.

when x = -1.281 , y = -1.281 - 2= -3.281.

An airplane climbs at an angle of 11o with the ground. Find the ground distance it has traveled when it has attained an altitude

dmitriy555 [2]

Answer:

Step-by-step explanation:

we use trigonometry to write:

400 x = tan ( 11 ∘ )

rearrange:

x = 400 tan ( 11 ∘ ) = 2057.8 ≈ 2058 ft
