Answer:
13
Step-by-step explanation:
All the lengths in triangle ADE are twice those in similar triangle ABC. So ...
x-1 = 2(6)
x = 13
9/10 of 50....." of " means multiply
9/10 * 50 = 450/10 = 45
Answer:
Q ' (3,4)
Step-by-step explanation:
When we reflect across the x axis, the y coordinate becomes -y
Q (3,-4) becomes Q' (3,- -4)
Q ' (3,4)
Answer:
14 3/5
Step-by-step explanation:
The way is simple add 4/5 and 4/5 together to get 1 4/5 then add 6 +7=13 then add 13 + 1 4/5 to get 14 3/5

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
