Answer:

Step-by-step explanation:

The angle at C is 90 degrees, and BCD is a right triangle, so we can applythe Pythagorean theorem here -- 60²+m²=65², so 65²-60²=m²=625. The possible values for m are 25 and -25, and since m can't be negative, 25 is our answer as 25 is the square root of 625

4,16,8,32,16,<br> What comes after

beks73 [17]

Your answer is 64.
If you look at it the pattern is:
Multiply by 4, then divide by 2
4 times 4= 16
16 divided by 2= 8
8 times 4= 32
32 divided by 2= 16
Now you would multiply by 4
16 times 4= 64
