Complete the statements about circle Z. A central angle, such as angle
of circle Z, is an angle whose vertex is

and whose sides are radii of the circle.

Angle

is not a central angle of circle Z.

The degree measure of an arc is

the degree measure of the central angle that intercepts it.

The measure of is
degrees

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
