Line EB is the mid segment of the triangle

EB and DC are parallel if angle EBA is equal to angle DCB

so

4x - 3 = 3x + 9  now solve for x

-3x          -3x

    x -3 =  + 9

       -3      -3  

    x      =   12

Now I know x and 3x +9, so sub in for x

3(8) + 9 = 32 + 9 = 41  


now we know angle EBA

and angle EBA and angle EBC are a linear pair meaning when I add them together they equal 180

so

angle EBA +  angle EBC = 180

     41         +        14y - 5   = 180 now solve for y

     36 + 14y = 180

    -36             -36

             14y = 144

              /14     /14

               y  =  10.28

You use the pythagorean theorem to calculate the missing sides.
formula: a^2+b^2=c^2
a=leg, b=leg, c=hypotenuse.
substitute the lengths in and solve for the missing length.
1. 5^2+12^2=c^2 simplify exponents 
    25+144=c^2    add
    169=c^2          square root both sides
    a.13
2. 8^2+b^2=10^2
    b.6
3. 15^2+20^2=c^2
    b.25
4. Distance formula 5sqrt2
