Will give brainliest! friends, i am thinking of four numbers such that the sum of all the four numbers is 31. only one of number is odd. the highest number minus the lowest number is 7. if you subtract the middle two numbers, it equals two. there are no duplicate numbers. what four numbers i am thinking of ?

A figure is located at A(0, 0), B(−3, −4), and C(−3, 0) on a coordinate plane.

This form a right triangle ( because vector AC(3, 0) is perpendicular with vector BC(0, 4) at C. You can check it by take multiplication of vector AC and BC, you would get: vector AC x vector BC = 3 x 0 + 0 x 4 = 0)

And as you know a cone is created by rotating a right triangle around its side (not hypotenuse). Here, the right triangle ABC has AB as hypotenuse and AB is not lying on rotating axis (x axis).

=> The 3D-shape, which is created by rotating ABC around x-axis would be a cone.

Hope this helps!
