Answer:

Step-by-step explanation:

The measurement of AC = 6pi

120/360 * pi * 2 * R = 6*pi                The pi values cancel out.

1/3 * 2 * R =  6                                    Multiply by  3

2R = 18                                               Divide by 2

R = 9

the circumference = 2 * pi * R

C = 2 * pi *9

C = 18 * pi

Now you want the measurement of arc AB

120 = 6 * pi

30 = x

120/30 = 6pi/x            Cross multiply

120 * x = 180 * pi         Divide by 120

x = 180 pi / 120

x = 3/2 * pi

So the measurement of arc AB = 1.5 * pi

Find the measure of an angle whose measure is 20° less than the measure of its supplement.
Tasya [4]
Supplementary = angles add up to 180
Measure = 20 less

Labelled as x + (x - 20) = 180

Solve.

x + (x - 20) = 180
             2x = 200
             /2      /2
               x = 100

Angle 1:             Angle 2:
x - 20                  x
100 - 20             100
80

Therefore the angle is 80 degrees.

Proof: 80 + 100 = 180 (supplementary)
100 - 80 = 20 (80 is less than supplement (100)

Hope I helped :))))

Find the distance between the points ( – 9, – 4) and ( – 4,8).
Dmitriy789 [7]

Answer:

Distance=13\ units

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two pints (x_1,y_1)\ and\ (x_2,y_2) is given by

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance between (-9,-4)\ and\ (-4,8).

d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13
