Answer:

y=61, x=112

Step-by-step explanation:

119+y=180

180-119=y

61=y

131+56+61+x=360

248+x=360

360-248=x

112=x

Find the midpoint M of the line segment joining the points A = (-7, -6) and B = (3, 4).

Colt1911 [192]

Answer:

The midpoint is (-2,-1)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

( -7+3)/2 = -4/2 =-2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(-6+4)/2 = -2/2 =-1

The midpoint is (-2,-1)

Suppose a sector of a circle with radius r has a central angle of θ. Since a sector is a fraction of a full circle, the ratio of

enot [183]

Answer:

Central angle of θ

$\dfrac{A}{\pi r^2} =\dfrac{\theta}{2\pi}$

$A=\dfrac{\theta r^2}{2}, (\theta$ in radians)$

Step-by-step explanation:

Suppose a sector of a circle with radius r has a central angle of θ.

Since a sector is a fraction of a full circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle of θ to the measure of a full rotation of the circle.

A full rotation of a circle is 2π radians.

This proportion can be written as: $\dfrac{A}{\pi r^2} =\dfrac{\theta}{2\pi}$

Multiply both sides by $\pi r^2$

$\dfrac{A}{\pi r^2} *\pi r^2=\dfrac{\theta}{2\pi}*\pi r^2$

Simplify to get:

$A=\dfrac{\theta r^2}{2}$

Where θ is the measure of the central angle of the sector and r is the radius of the circle.
