Question

Enter the number that belongs in the green box cd=

Answer 1

57 because it is right n mark ne brain list please

Answer 2

9

Explanation:

I think 9 since there’s a right angle, so there’s an assumed right angle on the other side of the line. 9 is the hypotenuse when AB is 3 so I think CD would also be 9 since BC is 3 as well.
