Step-by-step explanation:

4x+11+8x+1=180 (the two angles given is supplementary angles)

11x+12= 180

11x=168

x=168/11

x=15.27

<em><u>Answer:</u></em>

x = 14

<em><u>Step-by-step explanation:</u></em>

Same side interior angles are supplementary.

Therefore ,

              ( 4x + 11)° + ( 8x + 1 )° = 180 °

                  4x + 11 + 8x + 1 = 180

                       12x + 12 = 180

                        12x = 180 - 12

                             12x = 168

                                 x = 14

Which of the following is a solution of 4x2 = − 9x − 4?
nignag [31]
Get all on one side
add 9x+4 both sides
4x^2+9x+4=0
use quadratic formula
in form
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

a=4
b=9
c=4

x=\frac{-9+/- \sqrt{9^{2}-4(4)(4)} }{2(4)}
x=\frac{-9+/- \sqrt{81-64} }{8}
x=\frac{-9+/- \sqrt{17} }{8}
x=\frac{-9+ \sqrt{17} }{8} or \frac{-9- \sqrt{17} }{8}

aprox
x=-1.64039 or -0.6096

-5/8(-3/8 minus one fourth)
Ne4ueva [31]

The value of  \frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )= 25/64

<h3>What is fraction?</h3>

A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers.

\frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )

= -5/8 (-3/8 -2/8)

= -5/8 (-5/8)

= 25/64

Thus, \frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )= 25/64

The arc length of a sector is equal to four times the radius. Express the arc length s
Sveta_85 [38]

Answer:

Step-by-step explanation:

Given that,

The arc length is four times the radius

Let he radius be 'r'

Then, the arc length be 's'

The arc of a sector can be calculated using

s=θ/360 × 2πr

Then, given that s=4r

So, 4r = θ × 2πr / 360

Divide both side r

4 = θ × 2π/360

Then, make θ subject of formula

θ × 2π = 360 × 4

θ = 360 × 4 / 2π

θ = 720 / π

So, area of the sector can be determine using

A = θ / 360 × πr²

Since r = ¼s

Then,

A = (θ/360) × π × (¼s)²

A = (θ/360) × π × (s²/16)

A = θ × π × s² / 360 × 16

Since θ = 720 / π

A = (720/π) × π × s² / 360 × 16

A = 720 × π × s² / 360 × 16 × π

A = s² / 8

Then,

s² = 8A

Then,

s= √(8A)

s = 2 √2•A
