Suppose △abc and △def are similar and bc=6, ef=8, df-ac=1. find df.

DF=4

Just cause of math

Side DF = 4 units

Step-by-step explanation:

Similar triangles states that the triangles with equal corresponding angles and proportionate sides.

Given: ΔABC and ΔDEF are similar

Corresponding angles are;

,  

,

Proportionate sides are;

It is also given BC = 6 units , EF = 8 units and DF -AC = 1

Let AC = x units then;

DF = x +1 units.

Then, by definition of similar triangle ;

By cross multiply we have;

Using distributive property;  

6x + 6 = 8x

Subtract 6x on both sides we get;

6x + 6 -6x = 8x -6x

Simplify:

6 = 2x

Divide by 2 on both sides we get;

x = 3

DF = x +1  = 3+1 = 4

Therefore, the side DF is, 4 units
