Answer:
7
Step-by-step explanation:
because 105/15=7
84/12=7
28/4=7
so 1x7=7
The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
You need to know more information, not just the length of the hypotenuse.
If you know the length of one leg use Pythagoras theorem to find the other.
If you know the value of one other angle use trigononemtry
