Answer:

angles are 40 and 50

Step-by-step explanation:

let angles be 4x , 5x

4x + 5x = 90

x= 90 / 9

x= 10

angles are 4x , 5x

therefore angles are 40 , 50

Find the area of the shaded sector. Leave your answer in terms of π.

kozerog [31]

Answer:

18π ft^2

Step-by-step explanation:

The area of the circle is

pi *r^2

pi * 12^2

144pi

The part that is shaded is 45 degrees

An entire circle is 360 degrees

The fraction that is shaded is 45/360 = 1/8

Multiply the area by the fraction that is shaded

1/8 * 144 pi

18 pi

The slope of the line below is -2. Use the coordinates of the labeled point to find the point-slope equation of the line. (4, -6

r-ruslan [8.4K]

<u>Answer:</u>

The point-slope equation of the line is $y = -2x +2$ or $2x+y = 2$

<u>Solution: </u>

Let us assume that the slope is m and the y intercept of the line is b

Hence, $y=m x+b$ --------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (4,-6) and slope m = (-2)

Now putting the point (4,-6) in equation (i) we get,

$\Rightarrow-6 = m\times4 +b$

$\Rightarrow-6 = (-2)\times4 +b$

$\Rightarrow-6 = -8 +b$

$\Rightarrow-6+8 =b$

$\Rightarrow b = 2$

So, the equation of the line will be will be $y = -2x +2$ or $2x+y = 2$
