What is2,852.1 rounded to the nearest tenth
Trava [24]

Answer:

The Answer is 2852.1

Step-by-step explanation:

Rounding off means simplifying the number while keeping it close to its true value. The "tenth" position is the 1st number to the right after decimal place. The number in the tenth position is 1, and there are no numbers to the right after that.

If there were any numbers to the right of the tenth position we will have to follow the following rules to round off to the nearest tenth.

If the number to the right of tenth place is less than 5 then keep the same number in the tenth place.

If the number to the right of the tenth place is 5 or more than 5 add one to the number in the tenth position.

In here as there is 0 after tenth position we can keep the same number, that is 1.

So 2852.1 rounded off to the tenth position is 2852.1.

Gnom [1K]

Answer:

90 degree

Step-by-step explanation:

Let represent the measure of the third angle. Then, − can represent the measure of the second angle. The

sum of the two angles in the right triangle will be °.

− + =

− =

− + = +

=

=

=

The third angle is and therefore measures °. Replacing with in − gives () − = − = .

Therefore, the measure of the second angle is °. The measure of the third angle is °.
