How many 8's are in the answer and sum 5890/45?
When we asked to do an estimate for this number what is the difference show your estimate and write the difference to include the decimals 2dp.

Explanation:

There are countless, or infinite, 8's in the answer because the result is a periodic decimal:

The notation used for the periodic decimal numbers is an arc over the number that is repeated. In this case, it would be an arc over the first 8.

I will use a bar just to show how it is, but instead of a bar it should be an arc:

The estimation or approximation to two decimal places requires to drop the 8's since the third one and increase the second 8 to 9 (because the first decimal dropped is greater than or equal to 5).

Thus the estimated value would be 13.89.

The difference is:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

noncoplanar points are points that do not lie on the same line.
