Chords DE, EF, and FG are congruent.

Circle C is shown. Line segments C D, C E, C F, and C H are radii. Secants D E, E F, and F G are congruent. Angle H C D is 75 degrees, angle E C D is 67 degrees, and angle C F G is 56.5 degrees.

Determine the following measures.

mArc F G =
°
m∠ECF =
°

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

4+4+2x

or

2x+8

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
