A triangle has one leg that measures 12 cm and a hypotenuse 24 cm. Find the length of the other leg to the nearest tenth of cent
Minchanka [31]

9514 1404 393

Answer:

  20.8 cm

Step-by-step explanation:

The term "hypotenuse" suggests this triangle is a right triangle. Then the other leg can be found using the Pythagorean theorem:

  x^2 +12^2 = 24^2

  x^2 = 576 -144 = 432

  x = √432 ≈ 20.8 . . . cm

The other leg is about 20.8 cm.

_____

<em>Additional comment</em>

A right triangle with a short leg that is 1/2 the length of the hypotenuse is the "special" 30°-60°-90° right triangle. The longer leg is √3 times the length of the short leg: 12√3 ≈ 20.8 cm.

Snezhnost [94]

Answer: y = 3+b

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

y = x + b

Where:

y = total number of ceramic cats

x = actual number of ceramic cats

b=new ceramic cats bought

Replacing with the value given:

y = 3+b

Where y is the dependant variable and b the independent variable.

Feel free to ask for more if needed or if you did not understand something.
