90.69 rounded to the nearest tenth.
Go to the tenth value of the number and look to the number right of that. If it is 5 or higher, you round up; 4 or less, round down
9 is higher than 5 therefore you round up
90.69 becomes 90.7
Since the measurement of the longest side is missing we can use the pythagorean theorem to find the hypotenuse or longest side.
18^2 + 32^2 = c (hypotenuse) ^2
324 + 1,024 = c^2
1,348 = c^2
sqrt 1,348 = c
36.72 = c
i do not agree with ted because when you use the pythagorean theorem you do not get 47cm
this can be proved by
18^2 + 32 ^2 = 47^2
we already know the left side is 1,348
1,348 = 47^2
1,348 does not equal 2,209 which is 47 squared
