Arc Length = Ф/2π * 2πr

l = 2π/6π * 2 * 3.14 * 6

l = 1/3 * 37.68

l = 12.56

In short, Your Answer would be: 12.56 Feet

Hope this helps!

angle A and angle B are complementary angles. If m angle A = (x-16)degrees and m angle B = (3x+28)degrees, then find the measure

Ahat [919]

Answer:

$4x \times 448$

Step-by-step explanation:

$a = (x - 16)$

$b = (3x + 28)$

So you add :

$x \: and3x$

To get

$4x$

Then you do :

$16 \times 28$

To get :

$448$

Answer is :

$4x \times 448$

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:Angle \:\: of \:\: elevation= 30°$

____________________________________

$\large \tt Solution \: :$

Let the angle of elevation be " x "

$\qquad \tt \rightarrow \: \cos(x) = \dfrac{9 \sqrt{3} }{18}$

$\qquad \tt \rightarrow \: \cos(x) = \dfrac{ \sqrt{3} }{2}$

$\qquad \tt \rightarrow \: x = \cos {}^{ - 1} \bigg( \cfrac{ \sqrt{3} }{2} \bigg )$

$\qquad \tt \rightarrow \: x = 30 \degree \: \: or \: \: \cfrac{ \pi}{6} \: \: rad$

6. A rectangle has a perimeter of 62 feet. If its length is 9 feet longer than its width, find

Anastaziya [24]

Answer:

length = 20 ft, width = 11 ft

Step-by-step explanation:

let w be width, then length = w + 9

The opposite sides of a rectangle are equal , then

2w + 2(w + 9) = 62

2w + 2w + 18 = 62

4w + 18 = 62 ( subtract 18 from both sides )

4w = 44 ( divide both sides by 4 )

w = 11

and w + 9 = 11 + 9 = 20

then width = 11 ft and length = 20 ft
