ANSWER

16\pi \: sq.in

EXPLANATION

The area of a sector is calculated using the formula,

Area =  \frac{arc \: measure}{360 \degree}  \times \pi {r}^{2}

The arc measure is given as 45°

The radius of the circle is 8 inches.

We substitute to obtain,

Area =  \frac{45 \degree}{360 \degree}  \times \pi  \times {8}^{2}

Area =  \frac{1}{4}  \times 64\pi  = 16\pi

I have X, I just need Y.
GarryVolchara [31]

I'm getting x = 9.3223 which rounds to 9.32. Nice work.

Once you know the value of x, you can use the law of sines to find the value of y

sin(A)/a = sin(B)/b

sin(y)/7 = sin(70)/x

sin(y)/7 = sin(70)/9.3223

sin(y) = 7*(sin(70)/9.3223)

sin(y) = 0.70560358983312

y = arcsin(0.70560358983312)

y = 44.8783278056846

<h3>y = 44.88 approximately</h3>

------------------------------

If you must use the law of cosines, then here's how you could do it

c^2 = a^2 + b^2 - 2*a*b*cos(C)

7^2 = x^2 + 9^2 - 2*x*9*cos(y)

7^2 = (9.3223)^2 + 9^2 - 2*9.3223*9*cos(y)

49 = 86.90527729+81-167.8014cos(y)

49 = 167.90527729-167.8014cos(y)

-167.8014cos(y) = 49-167.90527729

-167.8014cos(y) = -118.90527729

cos(y) = -118.90527729/(-167.8014)

cos(y) = 0.708607182598

y = arccos(0.708607182598)

y = 44.8782954209662 ... this is slightly different from before due to rounding error

<h3>y = 44.88 approximately</h3>

The latest online craze is a new game, Khan on Seven. You get
aniked [119]

Answer:

The required inequality is 50w+100\geq 18000

Step-by-step explanation:

Consider the provided information.

You get  100 points for playing the game. In addition, you get  50 points for each seven-letter word you make with the ten letters you receive.

Let w represents a seven letter word which Sal will need to make to break the record.

She gets 100 points for playing the game and 50 points for each seven-letter

Therefore the total points earned is: 50w+100

Sal wants to break the record, and she needs 18,000 points or more.

Thus, the required inequality will be: 50w+100\geq 18000

Hence, the required inequality is 50w+100\geq 18000
