Answer:

EF = \sqrt{120}

Step-by-step explanation:

Since this triangle is right, we can use the pythagorean theorem to find the missing side length. The pythagorean theorem states that the square of the hypotenuse(DE) is equal to the sum of the squares on the legs(DF, EF). We can write:

DE^2 = DF^2 + EF^2

and substitute the values:

17^2 = 13^3 + EF^2

289 = 169 + EF^2

EF^2 = 120

EF = \sqrt{120}

Answer:

\sqrt{120}

Step-by-step explanation:

We can use the Pythagorean Theorem  to solve this question.

The Pythagorean Theorem: a^2+b^2=c^2, where a and b are the lengths, and c is the hypotenuse.

Using the image, we can write the equation: 13^2+b^2=17^2.

Simplify: 169+b^2=289.

Subtract 169 on both sides, we can know that b^2=120.

Square root on both sides, we can get b = \sqrt{120}.

Hope this helps!

The scale factor from S to M is 3/2 What is the scale factor from M to S
natita [175]

we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.

<h3></h3><h3>What is the scale factor from M to S?</h3>

Suppose we have a figure S. If we apply a stretch of scale factor K to our figure S, we can say that all the dimensions of figure S are multiplied by K.

So, if S represents the length of a bar, then after the stretch we will get a bar of length M, such that:

M = S*K

If that scale factor is 3/2, then we have the case of the problem:

M = (3/2)*S

We can isolate S in the above relation:

(2/3)*M = S

Now we have an equation (similar to the first one) that says that the scale factor from M to S is 2/3.

Then we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.
