Answer:
253.520
Step-by-step explanation:
Let us see what is the thousandths place...
It is the third digit to the right.
253.5198 rounded is about
253.520.
I can tell because you take the thousandths place, look at the one to the right of it, then if it is greater than 5, you make the thousandths place greater. Since it's a 9, you move the extra 10 thousandths to the next thing- the hundredths. and you get 253.520.

Answer:
A Solution is a value we can put in place of a variable (such as x) that makes the equation true.
Step-by-step explanation:
One angle of a triangle is 115 degrees.
The sum of the remaining angles is therefore 180-115=65°
If they are in a ratio of 2:11, then the smaller angle is 65*(2/(2+11))=10°
the larger angle is 65*(11/(2+11))=55°.
Check: 10+55=65°=180-115° ok.
Answer: the measures of the remaining angles are 10 and 55°
