Round 261.799 to the nearest tenth

The answer will be 261.8 because the tenths are the 1st digits after the decimal points which rounds up the 9s to the the 80 but you don’t have to include the zero on the final answer

Not gonna lie I think it could be 261.8 but that is definitely just a guess and not the right answer

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
