Solve for X. Geometry

Check the picture below.

so we have the inscribed angle D intercepting the arcBC, so 2D = arcBC.

let's keep in mind that a circle has a total of 360°, so the arc in red there, is 360° minus the others.

Step-by-step explanation:

Look at the picture.

The whole circle is 360°. Therefore we have the equation:

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

the answer is d. (1.2, -4.7) on edgn

hope this !
