Answer:

The correct option is b.

Step-by-step explanation:

The area of a rectangle is

A=length\times width

The area of rectangle is 48 square units and the width of the rectangle is 6 units.

48=length\times 6

Divide both sides by 6.

8=length

The length of the rectangle is 8.

In a right angled triangle,

\tan\theta=\frac{perpendicular}{base}

In triangle JKL,

\tan (\angle KLJ)=\frac{JK}{KL}

Opposite sides of a rectangle are same.

\angle KLJ=\tan^{-1}(\frac{6}{8})

\angle KLJ\approx 36.87

The measure of angle KLJ is 36.87. Therefore the correct option is b.

Solve for n.<br> n+ 1 = 4(n-8)<br> On=1<br> O n= 8<br> on = 11<br> On = 16
Lesechka [4]

Answer:

n = 11

Step-by-step explanation:

n+ 1 = 4(n-8)

<=> n + 1 = 4n - 4×8

<=> 4n - n = 1 + 4×8

<=> 3n = 33

<=> n = 11

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
