In circle d, ∠edh ≅ ∠edg.

circle d is shown. line segment f h is a diameter. line segments d e and d g are radii. lines are drawn from point e to point g and from point e to point h to form secants. the length of e j is 4 and the length of e h is 9. the measure of arc f e is 57 degrees and the measure of arc f g is 66 degrees.

what is the measure of arc e h?

114°
123°
228°
246°

true

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
