In order to answer that, we'd have to know the relationship between 'AB' and 'DC'.

You've told us nothing about how they're connected. Could there be a picture

that's supposed to go along with this question, maybe ?

If a over b equals c over d then is it possible that a plus b equals c plus d If not then give Mathematical Reason for that?

a/b=c/d =>ad=bc =>a =bc/d b =ad/c c =ad/b d =bc/a so if a+b=c+d is true => (bc/d)+(ad/c)=(ad/b)+(bc/a) => (bc2+ad2)/dc=(da2+cb2)/ab => ab(bc2+ad2)=dc(da2+cb2) and since ad=bc, => ab(adc+add) =dc(ada+adc) => abadc+abadd =dcada + dcadc => abadc-dcadc =dcada-abadd => (ab-dc)adc =(dc-ab)add ad cancels out => (ab-dc)c =(dc-ab)d => -(dc-ab)c =(dc-ab)d => -c = d so there's your answer :)


DC equals 10 what is the measure of angle AB?

10!


If ad is 10 units and ab is 8 units what is the measure of dc?

Given that AB = 8 units and AD = 10 units, we can use the ratios of corresponding sides in similar triangles to find the measure of DC. Since triangle ADC is similar to triangle ABC, the ratio of DC to AB is equal to the ratio of AD to AC. Thus, DC/8 = 10/AC. Solving for DC, DC = 8 * 10 / AC.


Dc equals 10 what is the value of AB?

You CAN'T calculate that, without additional information.

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.

What is the distances from a to b and c to b if a weather balloon b is directly 1500 meter airstrip extending from a to c the angle of elevation from a to b is 59 degrees and from c to b is 34 degrees?

Draw a line from b perpendicular to the airstrip at point d. This will form two right triangles: abd and cbd. Using trigonometry, here is a solution: ad + dc = 1500 meters, ad = 1500 - dc tan 59o = bd/ad = 1.664, so bd = 1.664ad tan 34o = bd/dc = .674, so bd = .674dc bd = 1.664ad = 1.664(1500 - dc) bd = 2946 - 1.664dc .674dc = 2946 - 1.664dc so, dc = 1068 and, ad = 1500 - dc = 1500 - 1068 = 431 cos 59o = .515, cos 59o = ad/ab = 431/ab, .515ab = 431, so ab = 837 meters cos 34o = .829, cos 34o = dc/bc, .829bc = 1068, so bc = 1288 meters

How do you find base of triangle?

let abc be the triangle with base bc. Consider it is equilateral triangle.. Now draw ad perpendicular to bc. Now ad equalls dc. Now tan 60 degree equalls ad/dc. With value of tan 60 and ad we can find dc. There fore bc equalls 2 * dc
