Dc equals 10 what is the value of bc?
10 over 3 <3 Angel
Ef is a median of isosceles trapezoid abcd find ef if ab is equal to 14 inches what is the length of ccd in terms of x?
It is not possible to answer the question because there is insufficient information. Also, there is no way of telling whether the trapezoid has AB parallel to DC (with AD and BC equal) or if AD is parallel to CB (with AB and DC equal). It is not clear what is meant by ccd. What is x? In any case, the length of one side, whichever it is, is not enough to answer the question.
To measure the distance dc across a pond a pond a surveyor takes points a and b so that ab is parallel to dc if ab equals 60 feet eb equals 48 feel and ed equals 80 feet find dc?
dc = 73.91261929 feet. 72
If EBEC and ABDC prove?
if EB=EC and AB=DC prove <A=<D
Abcd is a parallelogram ab equals bc and angle abc equals 90 degree explain why abcd is a square?
Opposite sides of a parallelogram are equal. So ab = dc and ad = bc. But you are also told that ab = bc. So all four sides are equal. Opposite angles of a parallelogram are equal. So abc =90 degrees implies that cda is 90 degrees. The remaining two angles add up to 360 - (abc + cda) = 180 degrees and both are equal. So they, too , must be 90 degrees each. So all four angles are equal. A parallelogram with four equal sides and four equal angles is called a square.
