Yes.
12-3 = 9
9
From least tor greatest, -15, -12, -9, -4
9 and 6 9+6 = 15 9-6 = 3
If the legs of a right triangle have measures of 9 and 12, the hypotenuse is: 15
Yes. 3, 4, 5 is a right triangle and by Pythagora's proof 32 + 42 = 52 Your 9, 12, 15 triangle has the same proportions scaled up 3 times.
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
Yes.
Yes if you mean dimensions of 9 by 12 by 15
It's a right angle triangle and its length is 12 units of measurement.
12
15 in
9
15
Using Pythagoras' theorem it is 15 feet
Using Pythagoras' theorem the hypotenuse of the right angle triangle works out as 15.
