Can someone please help and explain how to use the Pythagorean Theorem to prove a triangle is a right triangle.

marin [14]

Hi there!

For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2

And then find the root of the hypotenuse.

For example,

15^2 + 8^2 = the hypotenuse^2

Which equals, 225 + 64 = 289

Square root of 289 = 17

brilliants [131]

Answer:

37cm = 370 millimeters

37cm = 0.37 meter

37cm = 0.00037 kilometers

Step-by-step explanation:

$1cm = 10 millimeters \\\\1 cm = \frac{1}{100} meter\\\\1cm = \frac{1}{100000} kilometer\\\\$

37cm = 370 millimeters

Use The Scale Factor 1:12 To Find The Missing Dimension

adell [148]

Answer:

The length of the model is 21 inches

Step-by-step explanation:

we have

The scale factor

$\frac{1}{12}$

That means

1 unit in the model represent 12 units in the actual

1 inch in the model represent 12 inches in the actual

Remember that

$1\ ft=12\ in$

1 inch in the model represent 1 ft in the actual

The scale factor is

$\frac{1}{1}\ \frac{in}{ft}$

therefore

21 ft in the actual represent 21 inches in the model
