If a triangle has sides of lengths 5, 8 and 12, it is a right triangle. true or false

False.

Step-by-step explanation:

To see if these sides can form a right triangle, all we need to do is see if the following equation holds where is the larger measurement.   it doesn't really matter which you assign as 5 or 8.

So I'm choosing the following .

has to be 12 because 12 is the largest.

Now we got to see if holds.

That is, we need to see if holds.

That's totally false.  89 is definitely not 144 so 5,8, and 12 cannot be put together to form a right triangle.

could you reply to this with the question so i can ?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
