Step-by-step explanation:
In a 45-45-90 relation triangle the two shortest sides will have equal length, meaning:

To find the hypotenuse we must multiply the shortest side by
, both sides are equal so it doesn't matter which we multiply.

I don’t see nothing there
It would still be 80
Example:
<span>14,494 </span>
<span>To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: </span>
<span>10, 000 = ten thousand </span>
<span>4, 000 = thousands </span>
<span>400 = hundreds </span>
<span>90 = tens </span>
<span>4 = ones </span>
<span>Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.<span> </span></span>
