Question

In the unit Square, find the distance from E to stack A D with bar on top in terms of a and b the length of stack D F with bar on top text  and  end text stack A G with bar on top, respectively

  1. fraction numerator b over denominator a plus b end fraction    
  2. fraction numerator a b over denominator a plus b end fraction    
  3. fraction numerator a minus b over denominator a plus b end fraction    
  4. fraction numerator a over denominator a plus b end fraction    

hintHint:

L e t space x space b e space t h e space d e s i r e d space d i s tan c e space a n d space y space b e space t h e space d i s tan c e space f r o m space E space t o space D F space a s space s h o w n comma space
S i n c e space space capital delta space D space E space F space tilde space capital delta space G space E space A space comma space fraction numerator y over denominator 1 minus y end fraction space equals space a over b space semicolon space y space equals space fraction numerator a over denominator space a space plus space b space end fraction space S i n c e space H E space i s space p a r a l l e l space t o space s i d e space A G space o f space space capital delta space A D G comma space
x over b space equals space y over 1 semicolon space x space equals space fraction numerator a b over denominator a plus b end fraction

The correct answer is: fraction numerator b over denominator a plus b end fraction


    in the question we are asked to find the distance from E to AD in terms of a and b

    Therefore the correct option is choice 1

    ABCD is a Parallelogram, A E perpendicular D C text  and  end text C F perpendicular A D If DC=16cm, AE = 8 cm and CF = 10 cm, Find AD

    Here we used the concept of parallelogram and identified some concepts of corresponding attitudes. A parallelogram is a two-dimensional flat shape with four angles. The internal angles on either side are equal. So the dimension of AD is 12.8 cm.
