Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which va
solniwko [45]

Answer:

A = 15   B = 20   C = 25

D = 30   E = 40   F = 50

D = 3    E = 4     F = 5

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

A = 15

B = 20

C = 25

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.

D = A * n    E = B * n     F = C * n

Where

n = Scale\ Factor

Assume n = 2.

So, we have:

D = A * n    

D =15 *2

D = 30

E = B * n    

E = 20 * 2

E = 40

F = C * n

F = 25 * 2

F = 50

Assume n = \frac{1}{5}.

So, we have:

D = A * n    

D =15 *\frac{1}{5}

D = 3

E = B * n    

E = 20 * \frac{1}{5}

E = 4

F = C * n

F = 25 * \frac{1}{5}

F = 5

So, the possible sides are:

A = 15   B = 20   C = 25

D = 30   E = 40   F = 50

D = 3    E = 4     F = 5

Analyze the diagram below and complete the instructions that follow.
Flura [38]
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).
