Quanto misura l'area di un triangolo rettangolo isoscele con ipotenusa 8 cm? (urgente!)

1 answer:

7 0

Un triangolo rettangolo isoscele è metà quadrato. L'ipotenusa è la diagonale del quadrato, e i cateti sono i lati del quadrato.

Nei quadrati abbiamo

$d=\sqrt{2}l$

dove $d$ è la diagonale e $l$ è il lato. Usa le informazioni sopra che collegano la diagonale con l'ipotenusa e i cateti con i lati e potrai trovare i cateti, e quindi l'area.

Liula [17]

First, we’re going to use this formula:

2nd number - 1st number
————————————— x 100%
1st number

If we plug in the numbers to this equation:

23-20
———- x 100%
20

And subtract 23 to 20, the answer to this equation is:

3
—- x 100% = 15%
20

In this case, the percent of increase is 15%.

Order 34 × 102, 1.2 × 107, 8.11 × 10–3 and 435 from least to greatest.

andrey2020 [161]

I will assume that this question is about scientific notation (also assuming that the first number is 3.4*10^2), where you can arrange the numbers by the exponent of the 10, so from least to greatest:
$8.11*10^{-3}$ , $3.4*10^{2}$ , 435, and $1.2*10^{7}$
