Answer:

90°

Step-by-step explanation:

The sum of the arcs around the circle is ...

2x +4x +4x +2x = 360°

x = 360°/12 = 30°

The numbered angle is the average of the measures of the intercepted arcs, so is ...

(4x +2x)/2 = 3x = 3(30°) = 90°

The numbered angle is 90°.

What is the value of x? enter your answer in the box

Bas_tet [7]

They are vertical angles, and so they will equal the same <em>degrees</em>

set the two equal to another

2x + 2 = 3x - 52

Move all numbers with variables to one side, and all constant to the other

2x (-3x) + 2 (-2) = 3x (-3x) - 52 (-2)

2x - 3x = - 52 - 2

-x = -54

isolate the x, divide -1 from both sides

-x/-1 = -54/-1

x = -54/-1

x = 54

x = 54°

hope this helps

The sum of three numbers is 124. The third number is 3 times the first. The second number is 9 more than the first. What are the

Leona [35]

Answer:

23, 32, 69

Step-by-step explanation:

3 numbers x, y, z

z = 3x

y = x + 9

x+y+z=124

x + (x + 9) + 3x = 124

5x + 9 = 124

5x = 115

x = 23

y = 32

z = 69

check: 23 + 32 + 69 = 124

Graph y=47x−2 .<br><br> Use the line tool and select two points on the line.

irakobra [83]

Given y = 47x - 2

when x = 0, y = -2

when y = 0, x = 2 / 47

To draw the graph of y = 47x - 2, mark the points (0, -2) and (2/47, 0) and join the points.

The graph is attached.
