Answer 1

hint:



\[\Large x^2 + y^2 = z^2\]

Answer 2

In this case,

x = 100
y = 50
z = unknown (for now)

Answer 3

100^2 + 50^2 = 111.80 ?

Answer 4

You take the square root of 100^2 + 50^2, yes (I'm sure you did that but you didn't show it)

Answer 5

so round that to the nearest whole number to get 112
