If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?

no

because using Pytago theorem, we have:

20² + 40² ≠ 80²

80² + 20² ≠ 40²

80² + 40 ² ≠ 20²

Step-by-step explanation:

No, it does not follow the Pythagorean Theorem.

Step-by-step explanation:

A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.

the square root of 2000 equals about 44.7213595.

Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
