The two shortest sides of a right triangle are 10 in. And 24 in. long. What is the length of the shortest side of a similar righ

ivanzaharov [21]

If the two shortest sides of the triangle are 10in and 24in, then using Pythagoras' theorem, the longest side =
$\sqrt{10^2 + 24^2}$
= $\sqrt{676}$
= $26$

Now we know the two longest sides of the first triangle (24in and 26in) we can compare them with the two longest sides of the second triangle.
If $x$ = the scale factor the first triangle is enlarged by then
$26x = 39$ and $24x = 36$
⇒ $x = 1.5$

Finally, we need to multiply the smallest side of the first triangle by the scale factor to find the shortest side of the second triangle.
$10(1.5) = 15$
So the length of the shortest side of the other triangle is 15in.

You could, instead, calculate the length of the shortest side of the second triangle by using Pythagoras' theorem and ignoring the first triangle completely.

Use the pythagorean Theorem to prove the three sides of the triangle are the three sides of a right triangle. Show all of your w

weeeeeb [17]

Answer:

$2^{2}$ + $(2\sqrt{3}) ^{2}$ = 4 + 4 * 3 = 16 = $4^{2}$

Step-by-step explanation:

The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and $2\sqrt{3}$ , squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and $2\sqrt{3}$ being the legs of the right triangle, and 4 being the hypotenuse.
