Round 4.139 to the nearest hundredth.

4.14

Step-by-step explanation:

We are given that

4.139

We have to round 4.139  to the nearest hundredth.

Place of 4 in 4.139=unit

Place of 1 in 4.139=Tenth

Place of 3 in 4.139=Hundredth

Place of 9 in 4.139=Thousandth

Thousandth place is 9 which is greater than 5. Therefore, 1 will be added to hundredth place and all digits on left side of hundredth place remain same and digit on right side of hundredth place will be replace by 0.

Hence, the number =4.14 (nearest to hundredth)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

what is all that apply?
