For the pair of numbers, find a third whole number such that the three numbers form a Pythagorean triple.
30,40

50

Step-by-step explanation:

let a= 30

b= 40

c= ?

According to Pythagoras theorem

= +

= +

= 900 + 1600

= 2500

c=

c=50

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
