Online discussion groups do not allow members to develop critical thinking skills.
Group members are more likely to bond together as a group online than they would when meeting face-to-face.
Facilitating an online conversation may require even more work, so that participants continue engaging with one
another online.

Step-by-step explanation:

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.
