Given
bd=bc , bd=5x-26, bc=2x+1,and ac=43
find out the value of ab.
To proof
As given in question
bd=bc
put the value as given in the question
5x - 26 = 2x +1
5x - 2x = 26 +1
3x = 27
x = 9
Put the value of x in the bc equation
bc = 2× 9 + 1
= 19
as shown in diagram given below
ac = ab + bc
putting the value as given above
43 = ab + 19
ab = 43 -19
ab = 24
Hence proved
