Ajigsaw puzzle contains 50 pieces if joining any 2 pieces or groups is considered as one move what is the least amount of moves to put it together

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.

its 4 because 2 times 2 is 4, if you double the number two you get four
