Answer:
16.33 km
Step-by-step explanation:
The square length of hypotenuse is equal to the sum of two legs' square value:
|HI|^2 + |JI|^2 = |HJ|^2
|HI|^2 + (24.28)^2 = (29.26)^2
|HI|^2 + 589,5184 = 856,1476 (these are full values and will be easier to calculate with a calculator, if not we can use the approximate values: 589,5 and 856,1)
subtract 589,5184 from both sides
|HI|^2 = 266,5636 find the root of boths sides
HI = 16.33 approximately
