How do I solve the equation solving x would I equal them to each other?

Since they are both degrees of an angle they would be equal:

3x+80 = 7x-40

80 = 4x-40

120 = 4x

x = 120/4 = 30 degrees

7x-40 represents the central angle, the arc 3x+80 equals the central angle, it is the same, so 7x-40=3x+80. 7x-3x=80+40. 4x=120. X=30. Let’s plug it in. This can be a way to check the answer. We get: angle=170 and arc=170. So x=30 is correct.

Suppose an ant walks counterclockwise on the unit circle from the point to the endpoint of the radius that forms an angle of rad

serg [7]

Answer:

$\frac{4\pi}{3}$

Step-by-step explanation:

The original questions is suppose an ant walks counterclockwise on a unit circle from the point (1,0) to the endpoint of the radius that forms an angle of 240 degrees with the positive horizontal axis.

To find the distance ant walked we find the arc length of the sector with central angle 240 degree and radius =1 (unit circle)

arc length of a sector = $\frac{centralangle}{360} \cdot 2\pi r$

arc length of a sector = $\frac{240}{360} \cdot 2\pi(1)$

arc length of a sector = $\frac{2}{3} \cdot 2\pi$

$\frac{4\pi}{3}$

Look at the formula for the area of a circle below. . . A = 3.14(pi)r2 . . Which of the following equations can be used to solve

zaharov [31]

<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r). Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi). If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>
