The answer is 144 grams of zinc

Step-by-step explanation:

proportion zinc to copper = 4/17

4/17 = z/ 612

multiply the extremes

17 . z = 4 . 612

17 . z  = 2,448

z  = 2,448 / 17

z = 144

The answer is 144 grams of zinc

Always check your answer

4/ 17 = 144/612 = 0.235

step-by-step explanation:

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
