Find C round to the nearest tenth!!!! laws of sines!!!!! please help!​
kiruha [24]

Answer:

c =14.9 cm

Step-by-step explanation:

<C = 180 - (150 + 12)

<C = 180 - 162

<C = 18°

Law of sines:

sin (18) / c = sin(12) / 10

0.309 / c = 0.2079 / 10

c = 0.309 * 10 / 0.2079

c =14.9

The coordinates A(2, 1), B(7, 1), C(2, 4) form what type of polygon?
Digiron [165]

Step-by-step explanation:

Slope \:  of \:  AB =  \frac{1 - 1}{7 - 2}  =  \frac{0}{5}  = 0 \\  \\ Slope \:  of \:  BC =  \frac{4 - 1}{2 -  7}  =  \frac{3}{ - 5}  =  - \frac{3}{ 5}   \\  \\  \because \: Slope \:  of \:  AB \neq \: Slope \:  of \:  BC \\  \\  \therefore \: given \: points \: are \: non - collinear. \\

Hence, coordinates A(2, 1), B(7, 1), C(2, 4) form a triangle.

The rectangle below has an area of x^2-25x 2 −25 square meters and a length of x+5x+5 meters. What expression represents the wid
iris [78.8K]

Answer:  x - 5

Step-by-step explanation:

Since, the area of the rectangle = x^2 - 25=(x+5)(x-5)

Length of the rectangle = x+5

Let the width of the rectangle = b

Thus, the area of the rectangle = (x+5)\times b

⇒ (x+5)\times b=(x+5)(x-5)

⇒  b=\frac{(x+5)(x-5)}{(x+5)}

⇒ b=x-5

Therefore, the expression that shows the width of the rectangle = x-5
