Answer:
Step-by-step explanation:
Use the difference of squares formula.
If you combine -30 and +75 that will be 40. so GCF will be 40
The value of the length DF is 17
<h3>How to determine the length DF?</h3>
The statement Triangle ABC = Triangle ADF means that the triangles ABC and ADF are congruent triangles.
So, we have:
AB = AD
AC = A F
BC = DF
Given that BC = 17;
The equation BC = DF becomes
17 = DF
Rewrite as:
DF = 17
Hence, the value of the length DF is 17
