Which are measurements of the sides of a right triangle? . a. 202, 198, 40 . b. 28, 26, 12 . c. 17, 14, 6. d. all above?

Option A -  202, 198, 40

Step-by-step explanation:

To find :  Which are measurements of the sides of a right triangle?

Solution :

To form a right angle triangle the sides of the triangle satisfy the Pythagorean theorem.

i.e.

where, a is the longest side and b and c are the shorter sides.

Now, we apply this property in given sides and find the right angles.

Option A - 202,198,40

a=202 , b=198 , c=40

So, These sides form a right angle triangle.

Option B - 28,26,12

a=28 , b=26 , c=12

So, These sides do not form a right angle triangle.

Option C - 17,14,6

a=17 , b=14 , c=6

So, These sides do not form a right angle triangle.

Therefore, Option A is correct.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
