In triangle abc shown below, side ab is 10 and side ac is 8: triangle abc with segment joining point d on segment ab and point e on segment ac.
which statement is needed to prove that segment de is parallel to segment bc and half its length?
a. segment ad is 5, and segment ae is 4. (this is the right answer).
b. segment ad is 4, and segment ae is 8.
c. segment ad is 4, and segment ae is 5.
d. segment ad is 5, and segment ae is 2.

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x

How does the graph of y = 3x compare to the graph of y = 3-x?
