X=2π/3

Marina86 [1]

Answer:

$cos{\frac{2\pi}{3}}=-\frac{1}{2}$ .

Reference angle is $\frac{\pi}{3}$

Step-by-step explanation:

Given the value of x. we have to find the correct value of cosx.

$x=\frac{2\pi}{3}$

Now, we have to find the exact value of $cos{\frac{2\pi}{3}}$

$cos{\frac{2\pi}{3}}=cos(\frac{\pi}{2}+\frac{\pi}{6})$

$=-sin(\frac{\pi}{6})$

$=-\frac{1}{2}$

Now, we have to find the reference angle of $x=\frac{2\pi}{3}$ .

Since the angle $x=\frac{2\pi}{3}$ lies in second quadrant, the reference angle formula is

Reference angle= $\pi-given angle$ .

= $\pi-\frac{2\pi}{3}=\frac{\pi}{3}$

Given p || q and ∠4 = 130°, find the measure of angles 1, 2, 3, 5, 6, 7, and 8. Label on the diagram.

lana [24]

1 = 130
2 = 50
3 = 50
5 = 130
6 = 50
7 = 50
8 = 130

1 and 4 are the same because of the vertical angle

Please help i have to finish 15 assignments today including a final exam and i dont know what im doing

Sergio039 [100]

Answer:

(-1,6) ; (-2,11)

Step-by-step explanation:

y= x^2-2x +3

y= -5x + 1

the best way to proceed is substitute the value of y shows in the second equation in the first equation (general rule: substitute the value shows in the linear equation in the quadratic equation)

-5x + 1 = x^2-2x+3

x^2 +3x + 2 = 0

(x+2)(x+1) = 0

x = -2

x = -1

Solution 1

x = -1

y = 5 + 1 = 6

Solution 2

x = -2

y = 10 + 1 = 11

A rectangular room is 12 feet wider than its a long how many 1 ft.² tiles does it take to tile along the inside of the room let

Ludmilka [50]

Answer:

Number of of tiles will be $x^2+12x$ .

Step-by-step explanation:

Given:

let 'x' represent the length of the room.

Width is 12 feet wider than its length.

Width = $x+12$

Area of tiles = $1 ft^2$

We need to find number of tile along the inside of the room.

First we will find Area of room.

Area of room will be equal to length times width.

framing in equation form we get;

Area of room = $x(x+12)= x^2+12x$ sq. ft.

Now Number of Tiles will be equal to Area of room divided by Area of tile.

framing in equation form we get;

Number of Tiles = $\frac{x^2+12x}{1} = x^2+12x$

Hence Number of of tiles will be $x^2+12x$ .
