Answer:

His percent error is 16.6 %

Step-by-step explanation:

Trent estimated hie time to be 90m

Actual time was 75m

Error was 90m - 75m = 15m

Fractional error was then 15m/90m (divide)

So % error is 15/90 times 100 = (100/6)% = 16.6%

Julli [10]

Answer:

square

Step-by-step explanation:

You use the Pitagora's theorem to calculate the diagonals of the figure.

The diagonals are given by the distance NQ and MP.

By calculating the value of these diagonals you have:

d_{NQ}=\sqrt{(10-7)^2+(16-9)^2}=\sqrt{58}\\\\d_{MP}=\sqrt{(12-5)^2+(11-14)^2}=\sqrt{58}

These diagonlas are equal between them. Hence, the figure is a square
