Un bazin avand capacitatea de 63 dal se umple cu apa. se folosesc trei robinete. primul cu debitul de 2 ori mai mare decat al doilea si de 2 ori mai mic decat al treilea. daca primul robinet este lasat sa curga timp de 1 ora, al doilea o jumatate de ora, iar la treilea un sfert de ora, bazinul se umple. afla debitul fiecarui robinet.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
