Answer:

Answer: 64/3π -16/3)in²

Step-by-step explanation:

Area of segment equals area of sector minus area of isosceles triangle.

=0/360 x πr² -1/2r²sin (0)

Given; the length of chord, d=8√3in.

and the angle of the sector, 0=120

We can use the formula for calculating the length of a chord to find the radius of the circle.

D = 2r sin (0/2)

8√3= 2r (√3/2)

r=8in

Area of the segment= 120/360 x π x 8² - ½ x 8² sin (120)

= (64/3 π- 16 √3)in²

Enter the equation of the circle in standard form with center and radius given.\\\\\\\\\\\Center (8,0), radius = sqrt 3/////////
ehidna [41]

Answer:

 (x - 8)^2 + y^2 = 3.

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

Here h = 8, k = 0 and r^2 = (√3)^2 = 3

The answer is  (x - 8)^2 + (y - 0)^2 = 3

or (x - 8)^2 + y^2 = 3.

20x^2-30=4x solve for x
ankoles [38]

Answer:

x=1.3288 or -1.1288

Step-by-step explanation:

Given 20x^{2}-30=4x

    Subtract 4x from both sides

         20x^{2}-4x-30=0

Since we can factor out 2 from whole equation, let's factor out 2.

         2(10x^{2}-2x-15)=0

Divide with 2 on both sides

         10x^{2}-2x-15=0

We got the quadratic equation, we can solve for x using quadratic formula.

x=\frac{-b\pm\sqrt{b^{2}-4ac} } {2a}

x=\frac{2\pm\sqrt{2^{2}-4X10X(-15)} } {2X10}

x=\frac{2\pm\sqrt{604} }{20}

x=\frac{2\pm2\sqrt{151}}{20}

x=1.3288or-1.1288

Please help me!<br> Look at this diagram.
Rina8888 [55]

Answer:

if you look at carefully the left triangle has two same side. so left-angle of C is 180-130=50 degree 5x+5x+50=180 x=13 degree

Step-by-step explanation:

for right triangle again one angle is 50 degree and other is 6*13-(3)=75 degree so 75+50+(10y+5)=180 degree y=5 degree
