Answer:



Step-by-step explanation:
Given
Similar Triangles: ABC and DEF



Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.

Where

Assume n = 2.
So, we have:







Assume 
So, we have:







So, the possible sides are:



This is an isosceles triangle, so both legs are of length 5√2.
Use the Pyth. Thm. to find the length of the hypotenuse. Square 5√2 and double the result: 25(2) = 50; twice 50 is 100. The square of the length of the hyp. is 100, and so the length of the hyp is sqrt(100), or 10 (answer).
It equals -1
you have collect like terms the -7w+w
which give you -6w then you have to divide both sides by -6
which gives you -1
