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
dove è la diagonale e
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.
Answer:
The ships are 66 meters apart.
Step-by-step explanation:
For the sake of convenience, let us label ships A and B
As shown in the figure, the distances to the ships from right triangles.
The distance to the ship A is and it is given by
And the distance to the ship B is and is given by
Therefore, the distance between the ships A and B is
In other words, the ships are 66 meters apart.
Answer:
D
Step-by-step explanation:
CD is an angle bisector and divides the opposite side into segments which are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
3x = 9 ( divide both sides by 3 )
x = 3 → D
